Website Theme Change

On October 9, 2025 I changed this site's theme to what I feel is a much better design than previous themes. Some pages will not be affected by this design change, but other pages that I changed and new pages I added in the last several days need to have some of their photos re-sized so they will display properly with the new theme design. Thank you for your patience while I make these changes over the next several days. -- Ray Merriam

The Movie

Air Force was an early war production that stands above the similar efforts of the time, films such as Flying Tigers. It is a fictional account of a B-17 crew that is loosely based on the early months of the war. It depicts a group of B-17s departing Hamilton Field, California, on December 6, 1941, and flying right into the attack on Pearl Harbor, something that actually happened. The primary screenwriter, Dudly Nichols, was provided access to combat records for the 19th Bomb Group and exploits from that group were used as the basis of the movie.

The crew of the B-17, named the Mary Ann, then flies their bomber on to the Philippines via Wake Island. Once at Clark Field, the crew prepares for combat, but on the first mission flown the airplane is damaged, makes a belly landing, and the aircraft commander killed. As Clark Field is being evacuated, the Army orders the grounded Mary Ann burnt to avoid it falling into enemy hands. The crew struggles valiantly to protect and repair the airplane to fly it out, rather than see it destroyed. The climactic scene shows dramatic effort to fly the airplane out. Soon afterwards, the airplane crew locates a large Japanese fleet, and the Mary Ann sticks around long enough to radio its location. Soon the entire Army and Naval air forces are called in and they send the invaders to the bottom of the ocean.

There are a few peculiarities that stand out now, sixty years later. One is the way the screenwriters go out of their way to state that Japanese nationals in Hawaii aided the Pearl Harbor attackers, and that sabotage was committed by trucks running the flight line and destroying rows of P-40s. There were also depicted Japanese guerrillas in the jungles of Maui attacking the Mary Ann parked on a remote airfield. By May 1942 those accounts had been thoroughly discounted so why include them in the film? Also, the massive attack at the end of the film, in which the U.S. finally repays for Pearl Harbor, is overdone and almost ruins the film, at least for this 21st Century viewer. However, for the wartime audience that the film was aimed at, it no doubt provided hope for the eventual victory.

The film features some above-average model work, particularly depicting the Mary Ann coming in on a landing approach and snagging a fence. Some of the model depicted landings are a little "rough" but overall they are a cut above other films of the same era. By the way, most of the scenes depicting the destruction of the Japanese Navy at the end of the film were also miniatures shot in the ocean near Santa Barbara, California.

Also of note is the attention to detail for the scenes depicting the B-17 operations. Excellent interior shots, scenes of engine starts, crew interaction, and film continuity mark the film. The scenes where the crew is trying to start the number two engine with others pouring gas on the wheels to get the airplane to burn, all while the Japanese are attacking the field, are particularly good.

Note that this film was released as a DVD in June 2007 so it can be viewed in excellent video and audio quality. Extra features are a bit sparse, limited to two wartime cartoons, a radio interview, and the theatrical trailer. But that's not too important as the film is now available for purchase on DVD.

Anecdotal

The operational scenes were filmed in late July and August 1942 while based at Drew AAF, near Tampa Bay in Florida. Elements of the Combat Crew Training Center equipped with early B-17s that was based at Hendrick Field, Sebring, Florida, were used. Several P-39s and P-43s drawn from Drew Field were also used. T-6s also are used to depict Japanese fighters and an American dive bomber (A-25?).

Bruce Orriss' account in When Hollywood Ruled the Skies reveals that the cockpit mockup used in the film was originally constructed for Paramount's 1938 I Wanted Wings. There were numerous interior shots of the B-17 in the film that appear to be quite accurate.

The serial number shown for the starring B-17, the Mary Ann was 40-5564, a fictional number. This airplane remains unidentified but it is pretty conclusive that it was a B-17B that had been brought up to B-17C/D standards with fuselage and armament modifications, probably done by Boeing to many B-17Bs. A case can be made that the B-17B used was 38-583, but this is conjecture based upon serial number manipulation. 38-583 appears to have been assigned to Sebring from June through September 1942, though the record card indicates possible assignment to the Subdepot at Lowry Field, Colorado, during this period also.

Bruce Orriss tells that the scenes depicting the destruction at Hickam, Wake Island, and Clark Field, were shot adjacent to Drew AAF.

Production commenced on May 18, 1942 and wrapped on October 26, 1942. The movie was released on February 3, 1943, to good reviews. It was nominated for two Oscars and won one.

In the movie Air Force, when they cut the tail off and install a gun back there, Gig Young asks John Garfield if he has enough room. He replies, "Yeah, if you leave the tail wheel down." This is true. However, there is only 7" of space between the fuselage bottom and the bottom horizontal stab carry through spar at BLK #10. This little bit of information courtesy of Bill Stanczak.

After the film was completed, the AAF used B-17B 38-584 that starred as the "Mary Ann" in a war effort publicity tour. This photo shows in detail the reason that this B-17, often misidentified as a B-17C, was actually the earlier variant upgraded to a B-17C configuration. The location of the oil cooler scoops and cowling arrangement indicate those of a B-17B.

One of many great air-to-air shots of the small-tail B-17s that are sprinkled throughout the film. This view shows the Mary Ann in flight. Note the missing tail cone, which ties into the below scene where it was removed to add a tail gun. This was one of many little 'attention to detail' items that were missing in similar films of the era.

A still from the film showing the Mary Ann as it arrives at Hickam Field after the attack on Pearl Harbor. It is believed this and other similar scenes were shot near Tampa Bay, Florida, though the exact location is unknown.

To add a tail gun to the B-17B, the tail cone is shown being sawn off and replaced by a .50 caliber machine gun. That's John Garfield as the new tail gunner. I guess by this point in the war the wartime censors figured the Japanese knew these B-17s didn't have tail guns but didn't know how many B-17s we had, thus the fictional tail number on the Mary Ann.

Unusual in this film is that the B-17s actually drop bombs, and it sure looks like real anti-aircraft fire in these scenes. Either it was unusually good trick photography or some very trusting Air Corps pilot was promised that they wouldn't really aim at him when they shot the scene.

The big "10" on the tail gets painted out in this scene in the film as the Mary Ann's prepared for combat. The tail number represents an AAF serial of 40-5564, not a valid serial for any aircraft. The filmmakers went to great pains to show this airplane as having this serial number, including the film credits that listed the crew of "B-17 Plane Number 05564" and a navigator's log that showed the airplane as a B-17D with this serial. It turns out this airplane is actually B-17B 38-584.

One of the early ground shots in the film showing a pensive John Ridgely walking the flight line. A squadron of early B-17s used for flight training were employed in the production, shot in July and August 1942 just after the Battle of Midway. The overwhelming Allied victory at the end of the film, though, resembles the Battle of the Coral Sea of May 1942.

For those who enjoy seeing the early B-17s in action, Air Force is full of operational scenes of these airplanes. This scene shows the Mary Ann upon landing at Clark Field in the Philippines, though it is actually somewhere in Florida. The B-17B is dragging a fence after a short field landing, a nice touch, as are the squealing brakes noted as the airplane taxis by.

This is, at least to my eye, one of the few identifiable B-17s in the film, B-17B 39-001, in a takeoff scene. Note how the serial is only painted on the rudder and not the vertical stabilizer, a practice verified on photos of other early B-17s but not on the modified serial of the Mary Ann.

You'll never see the likes of this again: nine B-17Bs, Cs, and Ds in a mixed formation, probably shot offshore near Florida by Paul Mantz and Elmer Dyer. The camera platform used for this show is unknown, but may have been one of Mantz's special camera ships. Bruce Orriss notes that Mantz's Lockheed Orion, Boeing 100, and Stinson were all used for the filming. This scene depicts the flight from California to Hawaii early in the film.


Boeing B-17B Flying Fortress

Boeing B-17B Flying Fortress (BS 34) at March Field, Riverside, California, 1940.

The B-17B (299M) was the first production model of the B-17 and was essentially a B-17A with a larger rudder, larger flaps, and a redesigned nose and 1,200 hp (895 kW) R-1820-51 engines. The small, globe-like, machine gun turret used in the Y1B-17's upper nose blister was replaced with a .30 caliber (7.62 mm) machine gun, its barrel run through a ball-socket in the ten-panel Perspex nose glazing. This was held in place by both the socket's strength combined with a flexible interior support strap, which later became an aluminum-reinforced window pane. The Y1B-17's separate triangular-shaped bombardier's aiming window, located further back in the lower nose, was eliminated, replaced with a framed window panel in the lower portion of the nose glazing; this configuration was used on all Flying Fortress airframes up through the B-17E series. All B-17B aircraft were later modified at Boeing, being brought up to the B-17C/D production standard. While the new nose glazing still used only a single .30 caliber machine gun, two additional ball-sockets were installed in the nose, one in the upper left panel and another in a lower right. This three ball-socket layout was continued up through the B-17E series. During Army Air Corps service, the bulged teardrop-shaped machine gun blisters were replaced with flush-mounted Perspex side windows of the same type used in the B-17C/D series. Various aircraft had different levels of upgrades performed. Some of the "B" series Fortresses had only their bulged side blisters replaced with slide-out flush windows, while others also had their bulged upper blister changed to a much flatter, more aerodynamic Perspex window panel. In addition, some "B" series Fortresses also had ventral "bathtub turrets" (see the "C/D" section below) installed, replacing their lower, teardrop-shaped gun blisters.

Crew locations were rearranged, and the original pneumatic brake system was replaced with more efficient hydraulic brakes.

In October 1942 all in-service B-17B aircraft were redesignated RB-17B, the "R" indicating "Restricted". These aircraft were now used only for training, transport, messenger, and liaison duties. The "R" prefix became a designation for combat obsolescence.

Many of these RB-17B aircraft, along with at least one still-airworthy YB-17, were stationed at Sebring Airfield, where the exterior scenes were filmed for the Warner Bros. war drama Air Force (1943), directed by Howard Hawks, and starring (among others) John Garfield, Arthur Kennedy, Gig Young, and Harry Carey. The film's real star, however, was an RB-17B (United States Army serial number 38-584), carrying on its upper rudder the "security-conscious" false serial number "05564". It passed as a later model B-17D Flying Fortress, having had its machine gun blisters replaced and a lower "bathtub" ventral gun turret installed. Many of these aircraft can still be seen in both ground and aerial scenes during the film.

The "B" series Flying Fortress made its maiden flight on 27 June 1939. 39 were built in a single production run, but Army Air Corps serial numbers were scattered over several batches. This was because of limited government funding: The Army Air Corps could only afford to purchase a few B-17Bs at a time.

The B-17B Flying Fortress set an official non-stop coast-to-coast record for airplanes in 1937 by flying from California to New York in 9 hours, 14.5 minutes.

Only 39 B-17Bs were built, They were very similar in external appearance to the Y1B-17, the main changes being turbo-supercharged Wright Cyclone engines as standard, giving a significant performance increment, a larger, re-designed rudder for greater lateral stability at high altitudes, and a revised transparent nose with an optically flat panel in front of the bombsight. Many other changes took place under the skin. It was a step in the right direction.

Twenty-nine officers and 28 enlisted men of the U.S. Army Air Corps took off from Langley Field, Virginia, 10 November 1939, on a Friendship Flight to South America.

Boeing B-17A (Y1B-17A)

Boeing Y1B-17A in flight near Mt. Rainier, Washington state; 28 February 1938.

The aircraft that became the sole Y1B-17A was originally ordered as a static test bed. However, when one of the Y1B-17s survived an inadvertent violent spin during a flight in a thunderhead, Army Air Corps leaders decided that the bomber was exceptionally robust and that there would be no need for static testing. Instead, it was used as a testbed for enhancing engine performance on the new bomber. After studying a variety of configurations, use of a ventral-nacelle-mount turbocharger position was settled on for each of its four engines. A successive series of General Electric-manufactured turbochargers would equip B-17s as standard items, starting with the first production model, allowing it to fly higher and faster than the Y1B-17. When testing was completed, the Y1B-17A was reconfigured as the B-17A, serial number: 37-369.

Equipped with turbosuperchargers, the B-17A opened an entirely new field for bombardment and caused fighter plane design to follow suit.
