A 1936 photo (courtesy of Marc Salvisberg) of his 68 year old great-grandmother Rosa Inauen Rutz in front of a Fleet Model 2 at the original (Santa Venetia) location of the Marin County Airport.
The date of establishment of the original location of the San Rafael Airport / Marin County Airport has not been determined.
The earliest depiction which has been located of the original (Santa Venetia) location of the Marin County Airport
was a 1936 photo (courtesy of Marc Salvisberg) of his 68 year old great-grandmother Rosa Inauen Rutz in front of a Fleet Model 2.
According to Marc Salvisberg, “She flew often enough to have her own leather flying cap. The family lived a few miles up the road from the field.”
The original San Rafael Airport / Marin County Airport was not yet listed among active airfields in the 1945 AAF Airfield Directory (courtesy of Scott Murdock).
The earliest aerial photo which has been located of San Rafael Airport was a 1946 aerial view.
It depicted the field as having a single northeast/southwest unpaved runway,
with a small hangar & 4 light single-engine aircraft on the southwest side of the field.
A circa 1940s photo (courtesy of Marc Salvisberg) depicted 5 light aircraft in front of a hangar labeled “Marin County Airport”,
with hills visible immediately behind the hangar.
The 1948 San Francisco Local Aeronautical Chart (courtesy of Tim Zukas)
depicted Marin County Airport as having a 2,400' unpaved runway.
A 1948 aerial view depicted at least 2 light aircraft on the south side of San Rafael Airport.
An undated aerial view looking north at “San Rafael – Marin County Airport” from the 1950 Air Photo Guide (courtesy of Kevin Walsh).
It described Marin County Airport as having a 2,450' paved runway & 2,000' turf Runway 18/36,
and listed the manager as H.O. Tollefson.
A 1951 cartoon-style map depicted Tollefson Flying Service at Marin County Airport (courtesy of Kevin Walsh).
The 1951 San Francisco Sectional Chart (courtesy of Jonathan Westerling)
depicted Marin County Airport as having a 2,100' paved runway.
A 1951 photo depicted several Cessnas & a stylish 1951 Buick Roadmaster Sedan Model 72R at San Rafael Airport (courtesy of Marc Salvisberg).
A 1952 aerial view showed that San Rafael Airport remained intact, including the runway & hangar, but the field was completely devoid of aircraft,
possibly indicating it had closed already.
The 1955 USGS topo map did not depict San Rafael Airport, just an open space.
A 1958 aerial view depicted homes covering the site of the original San Rafael Airport.
A 1968 aerial view showed that another San Rafael Airport had opened less than a quarter-mile to the west,
on the opposite side of the Gallinas Creek.
A 2015 aerial view looking north shows the site of the original San Rafael Airport covered by homes.
The runway of the replacement San Rafael Airport, located on the opposite side of the Gallinas Creek, is visible at top-left.
The site of the original San Rafael Airport is located at the intersection of Adrian Way & La Pasada Way.
Thanks to Marc Salvisberg for pointing out this airfield.
San Francisco Bay Airport, San Rafael, CA
37.965, -122.505 (North of San Francisco, CA)
The earliest depiction that has been located of the San Francisco Bay Airport was a 1946 aerial view.
San Francisco Bay Airport was a little general aviation field
that served the residents of San Rafael, the largest city in Marin County.
It was apparently built at some point between 1944-46,
as it was not listed among active airfields in the 1944 US Army/Navy Directory of Airfields (courtesy of Ken Mercer).
The earliest depiction which has been located of the San Francisco Bay Airport was a 1946 aerial view.
It depicted the field as having a single northwest/southeast unpaved runway,
with several small buildings & at least 4 light aircraft on the south side of the field.
The earliest reference to the San Francisco Bay Airport which has been located
comes from George Harper, who recalled, “I continued my flight training at this airport.
I started on 11/22/47. I received my private & commercial ratings.
My instructors were R. F. Knapton & H. O. Talefson.
Note Talefson also in 1947 gave many check flights to Hamilton Field Air Force Pilots for their civilian pilot's licenses.
The aircraft we used for flight training were: Aeronca Champs & Chiefs, Piper J-3 Cubs, Super Cubs,
Super Cruisers, a Stinson Voyager, Taylor Craft, Stearman PT-17, a Vultee BT-13 and a Ryan PT-22.
I got to fly them ALL!
On 2 occasions we flew over Larkspur, a nearby city, to release rose petals over their Rose Festival Parade.”
San Francisco Bay Airport was not yet depicted on the 1947 USGS topo map.
The 1948 San Francisco Local Aeronautical Chart (courtesy of Tim Zukas)
depicted San Francisco Bay Airport as having a mere 1,900' unpaved runway.
A 1948 aerial view depicted at least 2 light aircraft on the south side of San Francisco Bay Airport.
The 1949 USAF Urban Area Chart depicted San Francisco Bay Airport as having a single northwest/southeast runway.
The 1950 USGS topo map depicted the San Francisco Bay Airfield as having a single northwest/southeast runway.
An undated aerial view looking north at San Francisco Bay Airport from the 1950 Air Photo Guide (courtesy of Kevin Walsh).
It described San Francisco Bay Airport as having a 1,800' paved east/west runway, and listed the manager as Charles Kleinclaus.

According to Jonathan Westerling, San Francisco Bay Airport was owned by Jimmy Rusch.
It had full services along with a small café on the south east side of the airstrip.
Flight lessons were offered by a Mr. & Mrs. Bob Short,
and several young pilots were trained there.
The airstrip served as home-base for several small businesses
including an aerial photography firm
and an air-ambulance service which imported patients from Northern California
seeking the more advanced medical facilities of the bay area.
When filming the movie "Blood Alley", John Wayne based his Cessna at the San Francisco Bay Airport.
The 12/8/52 issue of the Marin Independent Journal (courtesy of Jonathan Westerling)
reported that a single-engine Cessna 195 en route to Detroit
crashed into the canal adjacent to San Francisco Bay Airport.
Killed in the crash was Charles Kleinclaus Jr., part owner of the San Francisco Bay Airport.
A 1952 aerial view depicted 6 light aircraft on the south side of San Francisco Bay Airport.
The 1954 USGS topo map (courtesy of Kevin Walsh) depicted San Francisco Bay Airport at its heyday,
with 3 small buildings south of the east side of the runway.
An undated photo of a nice Grumman G44 Widgeon in front of a hangar which had “S.F. Bay Airport” painted on the roof
(photo courtesy of the Marin County Library, via Jonathan Westerling).
A short article about San Francisco Bay Airport appeared in the 3/26/55 issue of Marin Magazine
(thanks to Jocelyn Moss of the Marin Historical Society Library).
"The Airport is located at the end of Railroad Avenue
which runs north from San Francisco Boulevard at California Park.
It is managed by Jimmy Rusch who also has charge of maintenance.
Rusch reports that right now, pleasure flyers outnumber business flyers
who are also using the airport & their number is growing constantly.
Many flyers, however make an effort to combine business & pleasure,
something that they wouldn't have time to do if they traveled by automobile."
An undated (circa 1950s?) aerial view looking east at San Francisco Bay Airport (courtesy of Steve Mahaley),
showing a single runway with several small hangars along the south side.
The photo was found in 2007 hanging along the wall in the San Rafael City Hall.

on the 1965 San Francisco Local Aeronautical Chart (courtesy of Jonathan Westerling).
The 1966 USGS topo map continued to depict the San Francisco Bay Airport,
even though it had been closed for 7 years by that point.
The 1969 USGS topo map depicted new streets covering the site of San Francisco Bay Airport.
A 1968 aerial photo showed that development had covered the San Francisco Bay Airport site,
with not a trace remaining of the former airport.
An article entitled "Canal dredge reveals plane engine" by Jennifer Upshaw
in the 5/5/04 issue of the Marin Independent Journal (courtesy of Jonathan Westerling)
described how barge workers dredging private docks in the San Rafael Canal scooped up an airplane engine with its propeller still attached.
This most likely was the remains of a Cessna 195 which crashed in the canal adjacent to the San Francisco Bay Airport in 1952,
killing the airport owner.
A 2018 aerial view shows not a trace appears to remain of San Francisco Bay Airport.
Thanks to Jonathan Westerling for pointing out this airfield.
Hamilton Field / Hamilton AFB / Hamilton AAF (SRF), Novato, CA
38.055, -122.507 (North of San Francisco, CA)
Hamilton Field, as depicted on a 3/12/32 War Department Plan (courtesy of Kevin Walsh).
This large military airfield was located along the northern shore of San Francisco Bay.
With formal development beginning, it was named Hamilton Field in 1932.
Construction at Hamilton Field had begun in 1932,
with the airfield being originally designed to accommodate 4 bomb squadrons & their personnel.
The earliest depiction which has been located of Hamilton Field was a 3/12/32 War Department Plan (courtesy of Kevin Walsh).
It depicted 5 hangars & an apron on the west side of an irregularly-shaped landing field.
Captain John M. Davies' 70th Service Squadron arrived in December 1932 as the first squadron assigned to the base.
Hamilton Field was labeled as “U.S. Bombing Field” on a 1932 street map (courtesy of Kevin Walsh).
No airfield was yet depicted at the site of Hamilton AAF on the 1933 San Francisco Airway Map (courtesy of Chris Kennedy).
The earliest photo which has been located of Hamilton Field was a 9/10/34 aerial view looking southeast.
It depicted 9 large arch-roof hangars & many other buildings to the west.
A circa 1934 of the newly-constructed Hamilton Field hangars (courtesy of Kevin Walsh).
In 1934, the 7th Bombardment Group arrived to take station, having been transferred up from March Field.
The new base was designated that year as General Headquarters of the 1st Pursuit Wing.
A 5/12/35 photo of the dedication of Hamilton Field (courtesy of Kevin Walsh).
The field was ceremonially handed over by California Governor Merriam (left) to Brigadier General Henry 'Hap' Arnold (right).

An undated aerial view in The Airport Directory Company's 1937 Airports Directory (courtesy of Bob Rambo) looking west at Hamilton Field.
It depicted 7 large hangars adjacent to the runway.
The directory described Hamilton Field as having a 3,500' landing mat running parallel to the hangars,
as well as 2 shorter graded runways.
An undated U.S. Army photo from the 1937 Aeronautical Chamber of Commerce of America Aircraft Yearbook (courtesy of Kevin Walsh),
captioned “A great fleet of bombers: 35 Cyclone-powered Martin bombers & a Douglas amphibian in the Air Corps line up at Hamilton Field.”

A circa 1940 aerial view looking east at Hamilton Field (photographed in 2018 by Kevin Walsh from a display at Oakland Airport)
depicted multiple aircraft parked in front of the row of checkerboard-roofed hangars.
Hamilton Field was described in 1940 as "looking more like a modern residential suburb
of Spanish California homes than the Army's Pursuit Base for northern California."
It had by that time received $5 million in development.
At that time the field housed the 45th Air Base Group, the 20th Pursuit Group (Fighter),
the 35th Pursuit Group (Interceptor), and the 82nd Observation Squadron,
totaling over 4,000 officers & men.

During WW2, Hamilton Field was rapidly expanded to a wartime status,
with construction of additional barracks, mess halls, administration buildings,
warehouses, Link trainer buildings, schools, hospital & other structures.

The original caption read, "Airacobra training at Hamilton Field, California, for the 357th Fighter Group
before shipping out to England to join the Eighth Air Force in July 1943.
Group CO Col. Edward S. Chickering's P-39 is being started by the ground crew the hard way -
with the hand crank to get the inertia starter going."

The 4/1/44 US Army/Navy Directory of Airfields (courtesy of Ken Mercer) described Hamilton AAF as having an 8,000' hard-surfaced runway.
According to the 1945 Army Inventory List (courtesy of Rex Ricks), at that point Hamilton's property consisted of a total of 1,599 acres,
and it had auxiliary fields at Napa, Montague, & Willows.
A 1945 aerial view looking west at Hamilton depicted the exponential growth which the base experienced during WWII.
Dozens of Douglas C-54 Skymaster transports lined the parking ramp with a few other types.
The area to the lower right of the runway was known as the "pea patch" and showed the parking dispersal hardstands for fighter planes.
These revetments were designed to allow fighters to survive an initial attack and launch to defend the base.
In later years the "pea patch" was where mechanics performed engine tests on afterburner-equipped jet interceptors.
Steven Pricer recalled, “My father, Lt. Col. Donald Pricer was the CO at Hamilton of the Search & Rescue outfit after the war.”
In the postwar era, Hamilton Field was reassigned to the Continental Air Forces in 1945.
A circa 1946-49 photo by Don Reid (courtesy of Bruce Reid) of Hamilton Field's Base Operations & control tower attached to a hangar.
Note the legend indicating a field elevation of 2 feet below sea level.

Note the variety of aircraft outside on the ramp.
The February 1948 San Francisco Local Aeronautical Chart (courtesy of Tim Zukas)
depicted Hamilton AFB as having a, 8,000' paved northwest/southeast runway.
In the postwar era, Hamilton Air Force Base was modified to accommodate jet aircraft,
and it was reassigned to the Air Defense Command in 1951.
An amazing 8/16/52 aerial view (from the UCSB Library) depicted a large number of aircraft on the Hamilton AFB ramp.
Hamilton AFB, as depicted on the 1954 USGS topo map.
Richard Bickel recalled, “Hamilton AFB... I was an Air Traffic Control Radar technician there working on the ASR & PAR systems from 1956-58.
I witnessed the only emergency landing of a U-2 aircraft at that base during graveyard shift, in late 1958.
I had just finished a tune-up on the AN/FPN-16 PAR radar 100' from the edge of the runway.
I stepped out onto the top landing & was surprised to see a long slender 2-wheel glider floating down onto the runway, turning right onto the grass parking with one wing high in the air!”

In 1959 Hamilton's runway was upgraded to accommodate F-101 & F-104 fighter operations.
The April 1959 San Francisco Local Aeronautical Chart (courtesy of Paul Columbus)
depicted Hamilton AFB as having a single 8,000' paved northwest/southeast runway.
A 1961 aerial view looking southeast along Hamilton's massive ramp, showing T-33 T-Birds & F-101 Voodoos galore.
In 1961, Hamilton's 83rd & 84th Fighter-Interceptor Squadrons were both equipped with the McDonnell F-101B Voodoo.
In the foreground are 8 Lockheed T-33 Shooting Star proficiency trainers, also known as "T-Birds",
used by staff officers to use in their spare time to remain on flight status & thus get their flight pay.
A 1964 photo by Ben Brown (courtesy of Bill Eaton) of a Douglas A3 Skywarrior, probably from NAS Alameda,
just after arrival at Hamilton for the May 1964 open house.
In the words of Bill Eaton, "It is parked abeam either Hangar 3 or 5.
Note the checkerboard on the roof of the hangar - very 1930s.
The crew has placed their helmets ('bone domes') atop the canopy.
One gust of wind and they'd roll off & go 'crunch' on the ramp.
But it's May & there was probably little or no wind on such a gorgeous Spring morning in the Bay Area.
Think of how fun it was to fly up the Bay from Alameda in your A3 at maybe 1000 feet
on such a beautiful morning, then make a low pass down runway 30 at Hamilton,
pitch up, land, and taxi in while people ran over to take a picture.
Then your wife & kids drive up from Alameda in the 1963 Ford Country Squire & spend the day at the airshow with Dad -
in his flight suit looking like Steve Canyon."
An undated (circa 1960s) photo of USAF F-101B Voodoo interceptors in front of a Hamilton hangar.
In 1966 Hamilton's 349th Military Air Wing converted from the C-119 to the C-124,
and shortly thereafter a large Air Force Reserve C-124 maintenance hangar was built on the southeast end of the ramp.

showing an F-101 Voodoo crew performing a scramble from their alert shed at Hamilton.
Hamilton was reassigned to the Aerospace Defense Command in 1968.
A photo from the 8/22/69 Hamilton Intercept (courtesy of Kevin Walsh) of Hamilton Field engine mechanic Clayton Walsh (right)
and Msgt. Thomas Greene, supervisor of J-75 section, checking the installation of a #3 turbine wheel of a Convair F-106 Delta Dart engine.
Kevin Walsh recalled that his father was an “Engine Mechanic, making the transition from props to jets, naturally.
He also subbed for a few months at the test cell circa 1968, and I always thought that was a rather cool place.
When his 1950 Chevy was getting tired, circa 1960, he bought the Base's Red Cross' surplus 1956 Chevy!
Unfortunately it was then painted all in black, which made it feel like an oven during those summer trips across the central valley up to Tahoe.
And he'd bring home the odd asbestos tile or batting to cover the garden shed with... It's a wonder i'm alive!”
An undated (circa 1970?) photo of the beautiful Hamilton AFB gate (courtesy of Kevin Walsh).
A 1972 photo of an 84th Fighter-Interceptor Squadron Convair F-106A Delta Dart,
slowing to taxi speed on Hamilton's Runway 30 with the help of a drag chute.
A 1972 photo (courtesy of Kevin Walsh) at Hamilton Field.
Kevin noted the picture is of “My father, Clayton Walsh, at age 50, getting his 30-year award in the very hangar in which he worked most of those years!”
In September 1973 the F-106s of Hamilton's sole remaining squadron, 84th Fighter Interceptor Squadron, relocated to Castle AFB,
thus bringing to an end a glorious era in Marin County history.
Hamilton was reassigned to the Air Force Reserve in 1973.
A post-1973 aerial view looking southeast at Hamilton,
showing only a few aircraft still visible on the ramp.
Carl Kangas recalled, “My old squadron, the 336th TAS, was the last flying squadron (C-130s) at Hamilton.”
Hamilton Air Force Base was decommissioned in 1974.
The airfield was transferred to the Army as Hamilton Army Airfield,
the housing to the Navy & a 411-acre parcel to the General Services Administration (GSA) for public sale.
The Pacific Strike Team of the Coast Guard occupied 2 of the historic hangars.
The 1975 San Francisco Terminal Aeronautical Chart depicted Hamilton AFB as having a single 8,000' paved northwest/southeast runway.
A series of 3 photos (courtesy of Carl Kangas) of the last Air Force flight from Hamilton on 1/9/76, by a 336th TAS C-130 Hercules.
Carl reported the 1st photo shows “the briefing in front of base operations.
Left to right: Unidentified, Lt. Col. W. Craig (squadron commander), Capt. Bob Shepherd (aircraft commander), Capt. L. Reisinger (co-pilot).”
The 2nd photo shows “the crew of 61-971: Left to right: Capt. B. Shepherd (AC), Capt. L. Reisinger (CP) , Load Master [unverified], Sgt. C. Kangas (FE).”
The 3rd photo shows “the heavy tractor being loaded to be flown to March AFB.
After take off Bob Shepherd came around for a low pass for the cameras & pulled up to about a 50 degree angle.
All the while I am hoping the load master did a good job of chaining down that tractor.
When Hamilton was slated for closure, the squadron was moved to March AFB.
This was the last load of squadron equipment that we flew down.”
The 1980 USGS topo map depicted Hamilton's massive airfield,
but did not label it at all, strangely.
A 411-acre Hamilton parcel was sold by the General Services Administration in 1985.
The last photo which has been located showing aircraft at Hamilton AFB was a 1987 photo of the Wings of Freedom Airshow (courtesy of Kevin Walsh).
The Hamilton airfield evidently saw very little use in its last days,
as a 1987 aerial view showed Hamilton's huge ramps completely devoid of even a single aircraft.
A 1988 airport diagram of Hamilton, its last year of operation.
The 1988 Base Realignment & Closure (BRAC) closed the Hamilton airfield.
Extensive aviation facilities remained, including a wide 8,000' long runway,
a smaller crosswind runway, numerous dispersal parking pads,
extensive ramp areas, and 9 large hangars.
Controversy over future civilian use had developed between those supporting
its adaptation into a major civilian airport, those bitterly opposed to its continued use as an airfield at all,
and those holding varying intermediate degrees of opinion.
Hamilton AAF, as depicted on the 1990 San Francisco Sectional Chart (courtesy of Dann Shively).
Tim Tyler visited Hamilton Field in 1990.
"Back then, many of the old buildings were intact,
including a large number of decrepit looking wooden barracks apparently left over from the WW2 era.
That area was marked as 'Off Limits' and probably scheduled for demolition.
The airfield was looking pretty rough, but there were some Army/National Guard UH-1s on the ramp.
It was still somewhat of a military installation back then,
but mostly used to provide housing for the military service members
assigned to various active military installations (mostly Navy) that were still active in the Bay Area then."
The last photo which has been located showing the massive Hamilton airfield still intact was a 7/9/93 USGS aerial view looking north.
Although the field remained intact, no aircraft were visible.
Note the multiple WW2-era fighter dispersal pads east of the runway.

A 1997 photo by Kevin Walsh looking up at Hamilton Field's deteriorating abandoned control tower.
A 1997 photo by Kevin Walsh from Hamilton Field's control tower looking down on its rows of hangars.
Kevin reported on whether anything prevented access to the control tower: “Nothing at all! No locks or closed doors...
There were still a few blank paper forms lying about, too.”

A 1997 photo by Kevin Walsh looking southwest at Hamilton Field, “from the then-newly-built levee, looking at the old runway before it was flooded.”
A circa late 1990s aerial view looking northeast at Hamilton's hangars, ramp & runway.
In the late 1990s, the Hamilton Field property was redeveloped by the local government,
with all of the aviation facilities to be removed.
Given the extent of the aviation infrastructure at this base (which was all paid for by the taxpayers),
it is a shame to see it completely destroyed.

A 2002 photo by Tim Tyler of the "Future Home of the Hamilton Field History Museum".
Tim observed, “I came out to the old Hamilton AFB to see how much it'd changed since I last visited it in 1990.
Twelve years later, the base had changed a lot. First of all, it's no longer a base.
Many structures have been removed & replaced with a housing subdivision known as Hamilton Landing (nice pun)."

Tim remarked, “The historic old main hangars were somewhat intact.
Some are now offices, using the shell of the original hangar but completely rebuilt inside,
and others as of my April 2002 visit were empty shells.
Several other old AAF/AFB buildings were intact, and either awaiting destruction, or renovation."
A 2002 photo by Tim Tyler of the sign at the Coast Guard installation which remains at Hamilton Field.

Tim observed, “The USCG still has their Pacific Coast Strike Team there,
set up as a quick-response group to deploy to major oil spills or other maritime environmental hazards,
but unlike in the past, the team now can't just have some USCG HC-130s land at the field,
pull up to the CG area & pick up personnel & equipment to transport them to the incident scene."
A 2002 photo by Tim Tyler of the dike which has been constructed along the former airfield area of Hamilton Field.
Tim observed, “The ramp area & runways seemed to be somewhat intact,
though I understand the plan was to flood the area & turn it into a marsh."
Tim Tyler reported again in 2003 of a later visit to Hamilton:
"I went up to the old Hamilton AFB, parked my car by some of the hangars,
hoisted my bike over the seawall thing,
and then merrily rode my bike along the old ramp/runway/taxiway & hardstand areas,
checking out various old buildings & facilities located along the runway area.
It looks like they've got a lot of work to go before they ever just flood the whole area."
A 2003 photo by Tim Tyler, of what presumably was an MA-1 fire control system calibration barn,
located adjacent to the south side of Hamilton's runway.
Tim observed, "The first one is a sheet-metal hangar, attached to a small cinderblock building
and then a sheet-metal shed on the other side of it.
The hangar's aircraft door faced to the West, not to the East, which is the direction of the runway.
Interestingly, I estimate the hangar aircraft door width only being about 40' or 50'
which makes me think of an F-104, although the hangar wasn't long enough to fit an entire aircraft inside.
Some old stenciling read '84th FIS MA-1/ASQ-25 Scheduled Maint. W/C 14322.'"
The AN/ASQ-25 was the 'Airborne Weapon Control System' used by F-101, F-102, and F-106 aircraft.
The 84th FIS seems to have been at Hamilton from the late 1940s until 1973, when it moved to Castle AFB.
Tim observed, "I believe the small metal hangar & support building I came across at Hamilton
was the MA-1 (Fire Control System) Calibration Barn.
It would have been isolated from the alert hangars in order to not interfere with their MA-1s,
which might have been kept in standby mode while the aircraft were on alert."
Tim continued, "There were several old carbon dioxide 300cf bottles
inside the old hangar & small cinderblock building which connected the hangar
(based on the hangar door, complete with center notch for a vertical stabilator) with the shed/workshop type building.
There were a couple static discharge ground connections built into the concrete flooring,
at least one had a date of 'Sept 88' stenciled on it,
though there is a good chance the date is (19)68 instead of (19)88."

located adjacent to the south side of Hamilton's runway.
Tim observed, “Just 10 or 15 yards to the southeast of [the hangar on the south side of the runway]
was a fairly large, single story concrete blockhouse,
which had an air conditioning/water chiller/power room on the end,
and several large, open rooms inside.
Though long-abandoned & with lots of graffiti inside,
everything but the old AC/chiller room on the end was still secured.
I don't know what this structure was used for, but it's the only thing I saw which may fit the basic 'signature'
of being an old ADC/NORAD Operations type building."
Richard Vedas (stationed at Hamilton from 1960-65) reported in 2003,
"the large concrete block house on the south end of the runway…
This was the Armament & Electronics building which housed the Radar, Com Nav,
Data Link, and Instrument shops in the 1960s.
The F-101s used the MG-13 fire control radar, F-102s were equipped with the MG-10 weapons system
while the F-106s were MA1 systems.
All were built by Hughes Aircraft.
MG-10 & 13 systems were almost identical, while the MA1 system was more advanced.
The radar mockup windows faced to the east where we used radio antennas on the east side of the bay for targets.
The small building looks like a F-106 nose dock used for system calibration.
We did calibrations on the F-101s in the hangars."

"The operations building, Building 30, had a 552nd AEW&C GROUP emblem on the exterior door.
The 552nd was classified as a Group only between 1974-76."

Also note the hundreds of new houses which have been constructed right up to the hangars.

According to Brent Peircy, “To my knowledge it is one of the few original buildings that remained operational & didn't fall into disrepair.
I lived on the base from 1966-68 & we attended that Chapel,
and when I visited again in the summer of 1990,
the Chapel was still operational & in fine condition unlike most other buildings on the base which were in terrible condition.”

Nine hangars still stand.
The middle of the runway has been flooded, but significant portions remain on either end,
as well as numerous dispersal pads.

Carl Kangas reported, “All the old hangars have been renovated & converted into a business park;
by the number of cars in the parking lots it looks like business is thriving. The tower has been restored.”

Amazing to see such a massive airfield completely removed.
Ironically, in April 2014 dikes were intentionally breached to let large portions of the Hamilton Field site be flooded,
to restore wetlands from the previous century.

Many millions of dollars of aviation infrastructure, paid-for by the taxpayers, now intentionally destroyed.
A 10/18/17 photo by Rex Ricks looking northwest along the former Hamilton AFB hangars & ramp area.
Rex observed, “Today as I visited the former Hamilton Field, I thought about the massive fires that recently hit Wine Country in Northern California.
If Hamilton Field was still an airport, instead of a swamp, aerial tankers could have scooped up water from the adjacent San Pablo Bay to put out the fires.
I will forever wonder, 'How many additional lives and homes could have been saved if only Hamilton Field was still active?'
Instead the Novato NIMBY Nabobs led by then Marin County Supervisor & eventual California Senator Barbara Boxer thwarted any efforts for aviation reuse in the 1970s.
Not only did Boxer join the swamp in DC, she also turned a federally taxpayer funded air base into a federally taxpayer funded swamp. What a colossal waste of millions of our tax dollars.”
