3 June 1942: After a U.S. Navy PBY patrol bomber sighted a task force of the Japanese fleet approaching Midway Atoll, nine U.S. Army Air Force Boeing B-17E Flying Fortress heavy bombers of the 431st Bombardment Squadron (Heavy), 11th Bombardment Group (Heavy), under the command of Lieutenant Colonel Walter C. Sweeney, Jr., launched from the island at 1230 hours.
The B-17s were equipped with bomb bay “Tokyo tanks” and each was armed with four 600 pound (272 kilogram) bombs.
At 1624 hours, the bomber force located Admiral Raizo Tanaka’s Midway Occupation Group 570 miles (917 kilometers) west of the island. They attacked in three flights of three, at 8,000, 10,000 and 12,000 feet (2,440, 3,050 and 3,660 meters). Although they reported damage to several ships, in fact none were hit.

3 June 1942: At dawn, twenty-two U.S. Navy PBY-5A Catalina patrol bombers launched from Midway Island to search for a Japanese fleet which was expected to be heading toward the American island base. One of them, 44-P-4, (Bu. No. 08031) commanded by Ensign Jewell Harmon (“Jack”) Reid of Patrol Squadron 44 (VP-44), sighted Admiral Raizo Tanaka’s Midway Occupation Force, 700 nautical miles (1,296 kilometers) west of the atoll, shortly before 9:00 a.m.

The Catalina scouted the enemy task force, which they believed to be the “main body” of the Japanese fleet and radioed information back to their base. The task force consisted of 1 light cruiser, 12 transports carrying 5,000 soldiers, 11 destroyers, 2 seaplane tenders, 1 fleet oiler and 4 patrol boats.

The Consolidated PBY Catalina made its first flight on 28 March 1935, with chief test pilot William B. Wheatley in command. It was a twin-engine flying boat produced from 1936 to 1945. It was utilized primarily as an anti-shipping and anti-submarine patrol bomber and for search and rescue operations.

The PBY-5A was an amphibious variant equipped with retractable tricycle landing gear. It was 63 feet, 10-7/16 inches long (19.468 meters) with a wing span of 104 feet, 0 inches (31.699 meters) and overall height of 20 feet, 2 inches (6.147 meters). The parasol wing was mounted above the fuselage on a streamlined pylon and supported by four external braces. The wing has 6° incidence and the center section has no dihedral or sweep. The outer wing panels are tapered. There are no flaps. The total wing area is 1,400 square feet (130 square meters). The PBY-5A had an empty weight of 20,910 pounds (9,485 kilograms), and gross weight in patrol configuration of 33,975 pounds (15,411 kilograms). Its maximum takeoff weight (land) was 35,420 pounds (16,066 kilograms).

The PBY-5A was powered by two air-cooled, supercharged, 1,829.4-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1C3-G (R-1830-92) two-row 14-cylinder radial engines. These were rated at 1,200 horsepower at 2,700 r.p.m. at Sea Level for takeoff. The maximum continuous rating for normal operation was 1,060 horsepower at 2,550 r.pm., up to 7,500 feet (2,286 meters). The engines drove three-bladed Hamilton Standard controllable-pitch propellers with a 12 foot, 1 inch (3.683 meter) diameter through a 16:9 gear reduction. The R-1830-92 is 48.19 inches (1.224 meters) long, 61.67 inches (1.566 meters) in diameter, and weighs 1,465 pounds (665 kilograms).
The PBY-5A Catalina had a cruise speed of 124 miles per hour (200 kilometers per hour). Its maximum speed was 169 miles per hour (272 kilometers per hour) at Sea Level and 179 miles per hour (288 kilometers per hour) at 7,000 feet (2,134 meters). The service ceiling was 14,700 feet (4,481 meters) and maximum range was 2,545 miles (4.096 kilometers) at 117 miles per hour (188 kilometers per hour.).
The patrol bomber could carry 4,000 pounds (1,814 kilograms) of bombs or depth charges, or two torpedoes on hardpoints under its wing. Two Browning M2 .30-caliber air-cooled machine guns were mounted in a nose turret with 2,100 rounds of ammunition. A third .30-caliber machine gun was positioned in a ventral hatch with 500 rounds of ammunition. Two Browning AN-M2 .50-caliber heavy machine guns were mounted in the waist with 578 rounds of ammunition per gun.
3,305 Consolidated PBY Catalina’s were built, of which 802 were the PBY-5A variant. In addition to United States service, many other countries operated the Catalina during and after World War II. The last PBY in U.S. service was a PBY-6A which was retired 3 January 1957.
KLM Royal Dutch Airlines’ Douglas DC-3-194, PH-ALI, Ibis.
1 June 1943: British Overseas Airways Corporation (BOAC) Flight 777-A was a scheduled passenger flight from Lisboa-Portela de Sacavém Airport, in neutral Portugal, to Whitechurch Airport, Bristol, England. The airplane was a Koninklijke Luchtvaart Maatschappij N.V. (KLM Royal Dutch Airlines) Douglas DC-3-194 twin-engine, 21-passenger commercial airliner, serial number 1590, with British registration G-AGBB.

The DC-3 had been delivered to KLM by ship, the Holland-America passenger liner, SS Statendam, which arrived 11 September 1936. The airliner was assigned Netherlands registration PH-ALI and named Ibis. It was the first of ten DC-3s ordered by KLM, and it regularly flew a London–Amsterdam–Berlin schedule.
KLM’s DC-3s were configured with a three-seat flight deck. A third seat was placed behind the first pilot, for use by a radio operator/navigator. A chart table was behind the second pilot’s seat.

When Germany invaded Holland in May 1940, Ibis was flown to England and was then leased to BOAC. Once in England, it was re-registered G-AGBB. Although it remained a civil aircraft, Ibis was painted in the standard Royal Air Force dark green, dark brown and gray camouflage. The original KLM flight crew continued to fly the airliner for BOAC.

At about 12:45 p.m., a flight of eight Junkers Ju 88C fighters, which were patrolling the Bay of Biscay to protect transiting U-boats, encountered the camouflaged DC-3 and shot it down.
All those aboard, 13 passengers and 4 crew members, were killed. Actor, director and producer Leslie Howard, who portrayed “Ashley Wilkes” in the 1939 motion picture, “Gone With The Wind,” and R. J Mitchell, designer of the Supermarine Spitfire, in 1942’s “First of the Few,” was one of the passengers who died.

Focke-Wulf Fw 190 V1, W.Nr. 0001, D-OPZE, the first prototype. (Focke-Wulf Flugzeugbau AG)
1 June 1939: At Bremen, Germany, Focke-Wulf Flugzeugbau AG chief test pilot Hans Sander took the first prototype of a new fighter, Fw 190 V1, W.Nr. 0001, registration D-OPZE, for its first flight.
Dipl. Ing. Hans Sander
The Fw 190 was designed as a fast, light-weight fighter with a powerful engine, easy to maintain under field conditions and able to absorb a reasonable amount of combat damage. The landing gear had a wide track which improved ground handling and was an advantage when operating on unimproved airfields. The mechanism used the gear’s own weight to lower it into place. Another interesting feature was to use of pushrods and bearings in place of the common cables and pulleys used to operate the flight controls. This gave a more precise, responsive operation. Also, the recent introduction of vacuum forming allowed a large one-piece “bubble” canopy to be used rather than the acrylic plastic/metal framework which was used in other fighters, such as the Messerschmitt Bf 109.
Focke-Wulf frequently named its airplanes after birds. The Fw 190 was known as the Würger, or Shrike.
Fw 190 V1 (Versuchsflugzeug 1) was 8.730 meters (28 feet, 7¾ inches) long with a wingspan of 9.500 meters (31 feet, 2 inches). It weighed approximately 3,000 kilograms (6,615 pounds).

D-OPZE was powered by an experimental air-cooled, supercharged 55.4-liter (3,380.4 cubic inch) BMW 139 two-row, 18-cylinder, radial engine which produced 1,529 horsepower. This engine had been developed from the nine-cylinder Pratt & Whitney Hornet (R-1690) which Bayerische Motoren Werke AG (BMW) built under license. (A redesign of the BMW 139 engine resulted in the 14-cylinder BMW 801 which was used in the production Fw 190.)
The propeller was a three-bladed Vereingite Deutsche Metallwerke (VDM) variable-pitch unit with a diameter of 3.460 meters (11 feet, 4¼ inches). It was driven at 54% of engine speed through a gear reduction unit.
To minimize aerodynamic drag, the large radial engine was tightly cowled and a large propeller spinner used. Cooling air entered through an opening at the center of the spinner and a fan between the propeller and the front of the engine circulated air. This was unsatisfactory and was significantly changed with the second prototype.
After testing by Focke-Wulf at Bremen, Fw 190 V1 was flown to the Luftwaffe test site at Rechlin-Lärz Airfield. Its identification markings were changed to FO+LY. Later, they were changed again, to RM+CA. V1 continued to be used for testing until 29 March 1943.

The Fw 190 was the most effective of Germany’s world War II fighters. More than 20,000 were built in 16 variants. The Focke-Wulf factory at Marienburg and the AGO Flugzeugwerke at Oschersleben were frequently attacked by Allied bombers.

A Focke-Wulf Fw 190 G-3 fighter bomber, W.Nr. 160016, which had been captured in Italy, was flight tested by the U.S. Army Air Force at Wright Field, Ohio, from 25 March to 15 April 1944, flown by Major Gustav Edward Lundquist, U.S. Army Air Force. In a report dated 26 May 1944, it was described as having a length of 29.1 feet (8.87 meters) and wingspan of 34.5 feet (10.52 meters), and was tested with maximum gross weight of 8,535 pounds (3,871 kilograms).
This aircraft was powered by an air-cooled, supercharged and fuel-injected 41.744 liter (2,547.4 cubic inch) BMW 801-D two-row, fourteen-cylinder radial engine which produced 1,750 horsepower at 2,700 r.p.m. with 41.1 inches of manifold pressure (1.39 bar). It could climb at 4,000 feet per minute (20.32 meters per second) and reach 20,000 feet (6,096 meters) in 7.3 minutes. 160016 had a maximum airspeed of 415 miles per hour (668 kilometers per hour) at 22,000 feet (6,706 meters). The service ceiling was 36,100 feet (11,003 meters).
The fighter was described to have performance “definitely weaker than standard AAF fighters at altitudes above 28,000 feet.” [8,534 meters]
The Fw 190 G-3 was armed with two Waffenfabrik Mauser AG MG151/20 20 mm autocannon with 550 rounds of ammunition.

(Two months later, Major Lundquist was in Europe, flying with the 486th Fighter Squadron, 352nd Fighter Group. On 29 July 1944, his North American Aviation P-51D-5-NA Mustang, 44-13395, was shot down by a Messerschmiit Bf 109 G-6 near Merseberg, Germany. Lundquist was captured and remained a Prisoner of War until the end of World War II. He was officially credited with 2 enemy aircraft destroyed. After the war, he returned to Wright Field and flight test. On 2 September 1946, Major Lundquist won the Thompson Trophy Race (J Division) while flying a Lockheed P-80A Shooting Star. Remaining in the Air Force for 29 years, he rose to the rank of brigadier general.)

A Boeing B-17F Flying Fortress takes off from Boeing Field, Seattle, Washington, 1942.
30 May 1942: The Boeing B-17F Flying Fortress makes its first flight. B-17F-1-BO 41-24340 was the first of a new series of the famous World War II bomber. While visually similar to the B-17E, it had more than 400 improvements based on early wartime experience with the B-17D and B-17E.
The Boeing B-17F Flying Fortress was a four-engine heavy bomber operated by a flight crew of ten. It was 74 feet, 8.90 inches (22.781 meters) long with a wingspan of 103 feet, 9.375 inches (31.633 meters) and an overall height of 19 feet, 1.00 inch (5.187 meters). The wings have 3½° angle of incidence and 4½° dihedral. The leading edge is swept aft 8¾°. The total wing area is 1,426 square feet (132.48 square meters). The horizontal stabilizer has a span of 43 feet (13.106 meters) with 0° incidence and dihedral. Its total area, including elevators, is 331.1 square feet (12.18 square meters).

The B-17F was powered by four air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.876 liters) Wright Cyclone C9GC (R-1820-97) nine-cylinder radial engines with a compression ratio of 6.70:1. (Early production B-17Fs were equipped with the Wright Cyclone G666A (R-1820-65). Both variants had the same power ratings.) The engines were equipped with remote General Electric B-22 turbochargers capable of 24,000 r.p.m. The R-1820-97 was rated at 1,000 horsepower at 2,300 r.p.m. at Sea Level, and 1,200 horsepower at 2,500 r.p.m. for takeoff. The engine could produce 1,380 horsepower at War Emergency Power. 100-octane aviation gasoline was required. The Cyclones turned three-bladed, constant-speed, Hamilton-Standard Hydromatic propellers with a diameter of 11 feet, 7 inches (3.835 meters) through a 0.5625:1 gear reduction. The R-1820-97 engine is 47.80 inches (1.214 meters) long and 55.10 inches (1.399 meters) in diameter. It weighs 1,315 pounds (596 kilograms).

The B-17F had a cruising speed of 200 miles per hour (322 kilometers per hour). The maximum speed was 299 miles per hour (481 kilometers per hour) at 25,000 feet (7,620 meters), though with War Emergency Power, the bomber could reach 325 miles per hour (523 kilometers per hour) at 25,000 feet for short periods. The service ceiling was 37,500 feet (11,430 meters).
With a normal fuel load of 1,725 gallons (6,530 liters) the B-17F had a maximum range of 3,070 miles (4,941 kilometers). Two “Tokyo tanks” could be installed in the bomb bay, increasing capacity by 820 gallons (3,104 liters). Carrying a 6,000 pound (2,722 kilogram) bomb load, the range was 1,300 miles (2,092 kilometers).
Many of the .50-caliber machine guns arming the B-17F Flying Fortress are visible in this photograph. (U.S. Air Force)
The B-17F Flying Fortress was armed with up to 13 air-cooled Browning AN-M2 .50-caliber machine guns. Power turrets mounting two guns each were located at the dorsal and ventral positions. A pair of machine guns were mounted in the tail, and single guns on flexible mounts were placed in the nose, radio compartment, and right and left waist positions.

An 8th Air Force study found that body armor prevented approximately 74 percent of wounds in protected areas. Once adopted in World War II, body armor reduced the rate of wounds sustained by aircrews on missions by 60 percent. Besides saving lives, body armor boosted aircrew morale during stressful missions over enemy territory.” (U.S. Air Force)A gunner fires the two Browning .50 caliber machine guns of his ball turret.

LIFE Magazine)
The maximum bomb load of the B-17F was 20,800 pounds (9434.7 kilograms) over very short ranges. Normally, 4,000–6,000 pounds (1,815–2,722 kilograms) of high explosive bombs were carried. The internal bomb bay could be loaded with a maximum of eight 1,600 pound (725.75 kilogram) bombs. Two external bomb racks mounted under the wings between the fuselage and the inboard engines could carry one 4,000 pound (1,814.4 kilogram) bomb, each, though this option was rarely used.
Probably the best known individual combat airplane, this is Boeing B-17F-10-BO Flying Fortress 41-22485, Memphis Belle, in flight over England, 1943. (U.S. Air Force)
The B-17 Flying Fortress first flew in 1935, and was in production from 1937 to 1945. 12,731 B-17s were built by Boeing, Douglas Aircraft Company and Lockheed-Vega. (The Manufacturer Codes, -BO, -DL and -VE, follow the Block Number in each airplane’s type designation.) 3,405 of the total were B-17Fs, with 2,000 built by Boeing, 605 by Douglas and 500 by Lockheed-Vega.
Only three B-17F Flying Fortresses remain in existence.
