B-17 Flying Fortress Game Free Download

The Boeing B-17 Flying Fortress is an American four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the American four-engined Consolidated B-24 Liberator and the German multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft.

In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, which were introduced into service in 1938. The B-17 evolved through numerous design advances[4][5] but from its inception, the USAAC (later, the USAAF) promoted the aircraft as a strategic weapon. It was a relatively fast, high-flying, long-range bomber with heavy defensive armament at the expense of bombload. It also developed a reputation for toughness based upon stories and photos of badly damaged B-17s safely returning to base.

The B-17F variants were the primary versions flying for the Eighth Air Force to face the Germans in 1943 and had standardized the manned Sperry ball turret for ventral defense, also replacing the earlier, 10-panel framed bombardier's nose glazing from the B subtype with an enlarged, nearly frameless Plexiglas bombardier's nose enclosure for improved forward vision.

Late in World War II, at least 25 B-17s were fitted with radio controls and television cameras, loaded with 20,000 lb (9,100 kg) of high explosives and designated BQ-7 "Aphrodite missiles" for Operation Aphrodite against bombing-resistant German bunkers. The operation, which involved remotely flying the Aphrodite drones onto their targets by accompanying CQ-17 "mothership" control aircraft, was approved on 26 June 1944, and assigned to the 388th Bombardment Group stationed at RAF Fersfield, a satellite of RAF Knettishall.[74]

The B-17's greatest success in the Pacific was in the Battle of the Bismarck Sea, in which aircraft of this type were responsible for damaging and sinking several Japanese transport ships. On 2 March 1943, six B-17s of the 64th Squadron flying at 10,000 ft (3,000 m) attacked a major Japanese troop convoy off New Guinea, using skip bombing to sink Kyokusei Maru, which carried 1,200 army troops, and damage two other transports, Teiyo Maru and Nojima. On 3 March 1943, 13 B-17s flying at 7,000 ft (2,000 m) bombed the convoy, forcing the convoy to disperse and reducing the concentration of their anti-aircraft defenses. The B-17s attracted a number of Mitsubishi A6M Zero fighters, which were in turn attacked by the P-38 Lightning escorts. One B-17 broke up in the air, and its crew was forced to take to their parachutes. Japanese fighter pilots machine-gunned some of the B-17 crew members as they descended and attacked others in the water after they landed.[124] Five of the Japanese fighters strafing the B-17 aircrew were promptly engaged and shot down by three Lightnings, though these were also then lost.[125] The allied fighter pilots claimed 15 Zeros destroyed, while the B-17 crews claimed five more.[124][126] Actual Japanese fighter losses for the day were seven destroyed and three damaged.[127][128] The remaining seven transports and three of the eight destroyers were then sunk by a combination of low level strafing runs by Royal Australian Air Force Beaufighters, and skip bombing by USAAF North American B-25 Mitchells at 100 ft (30 m), while B-17s claimed five hits from higher altitudes.[129] On the morning of 4 March 1943, a B-17 sank the destroyer Asashio with a 500 lb (230 kg) bomb while she was picking up survivors from Arashio.[130]

A 1943 survey by the USAAF found that over half the bombers shot down by the Germans had left the protection of the main formation.[136] To address this problem, the United States developed the bomb-group formation, which evolved into the staggered combat box formation in which all the B-17s could safely cover any others in their formation with their machine guns. This made a formation of bombers a dangerous target to engage by enemy fighters.[137] In order to more quickly form these formations, assembly ships, planes with distinctive paint schemes, were utilized to guide bombers into formation, saving assembly time.[138][139] Luftwaffe fighter pilots likened attacking a B-17 combat box formation to encountering a fliegendes Stachelschwein, "flying porcupine", with dozens of machine guns in a combat box aimed at them from almost every direction. However, the use of this rigid formation meant that individual aircraft could not engage in evasive maneuvers: they had to fly constantly in a straight line, which made them vulnerable to German flak. Moreover, German fighter aircraft later developed the tactic of high-speed strafing passes rather than engaging with individual aircraft to inflict damage with minimum risk.[citation needed] As a result, the B-17s' loss rate was up to 25% on some early missions. It was not until the advent of long-range fighter escorts (particularly the North American P-51 Mustang) and the resulting degradation of the Luftwaffe as an effective interceptor force between February and June 1944, that the B-17 became strategically potent.[citation needed]

To rectify the Fw 190's shortcomings, the number of cannons fitted was doubled to four, with a corresponding increase in the amount of ammunition carried, creating the Sturmbock bomber destroyer version. This type replaced the vulnerable twin-engine Zerstrer heavy fighters which could not survive interception by P-51 Mustangs flying well ahead of the combat boxes in an air supremacy role starting very early in 1944 to clear any Luftwaffe defensive fighters from the skies. By 1944, a further upgrade to Rheinmetall-Borsig's 30 mm (1.2 in) MK 108 cannons mounted either in the wing, or in underwing, conformal mount gun pods, was made for the Sturmbock Focke-Wulfs as either the /R2 or /R8 field modification kits, enabling aircraft to bring a bomber down with just a few hits.[105]

The U.S. did not offer B-17s to the Soviet Union as part of its war materiel assistance program, but at least 73 aircraft were acquired by the Soviet Air Force. These aircraft had landed with mechanical trouble during the shuttle bombing raids over Germany or had been damaged by a Luftwaffe raid in Poltava. The Soviets restored 23 to flying condition and concentrated them in the 890th Bomber Regiment of the 45th Bomber Aviation Division,[155] but they never saw combat. In 1946 (or 1947, according to Holm), the regiment was assigned to the Kazan factory (moving from Baranovichi) to help the Soviet effort to reproduce the more advanced Boeing B-29 as the Tupolev Tu-4.[156]

During the last year of World War II and shortly thereafter, the United States Navy (USN) acquired 48 ex-USAAF B-17s for patrol and air-sea rescue work. The first two ex-USAAF B-17s, a B-17F (later modified to B-17G standard) and a B-17G were obtained by the Navy for various development programs.[161] At first, these aircraft operated under their original USAAF designations, but on 31 July 1945 they were assigned the naval aircraft designation PB-1, a designation which had originally been used in 1925 for the Boeing Model 50 experimental flying boat.[169]

B-17s were used by the CIA front companies Civil Air Transport, Air America and Intermountain Aviation for special missions. These included B-17G 44-85531, registered as N809Z. These aircraft were primarily used for agent drop missions over the People's Republic of China, flying from Taiwan, with Taiwanese crews. Four B-17s were shot down in these operations.[172]

Many pilots who flew both the B-17 and the B-24 preferred the B-17 for its greater stability and ease in formation flying. The electrical systems were less vulnerable to damage than the B-24's hydraulics, and the B-17 was easier to fly than a B-24 when missing an engine.[179] During the war, the largest offensive bombing force, the Eighth Air Force, had an open preference for the B-17. Lieutenant General Jimmy Doolittle wrote about his preference for equipping the Eighth with B-17s, citing the logistical advantage in keeping field forces down to a minimum number of aircraft types with their individual servicing and spares. For this reason, he wanted B-17 bombers and P-51 fighters for the Eighth. His views were supported by Eighth Air Force statisticians, whose mission studies showed that the Flying Fortress's utility and survivability was much greater than those of the B-24 Liberator.[142] Making it back to base on numerous occasions, despite extensive battle damage, the B-17's durability became legendary;[140][141] stories and photos of B-17s surviving battle damage were widely circulated during the war.[142] Despite an inferior performance and smaller bombload than the more numerous B-24 Liberators,[180] a survey of Eighth Air Force crews showed a much higher rate of satisfaction with the B-17.[181]

On November 5, 1945, it was withdrawn from service and shipped to Altus, Oklahoma, for disposal. There, 42-29782 sat until 1946, when the War Assets Administration transferred the airplane to Stuttgart, Arkansas, for display as a War Memorial. Stripped of its turrets, guns, and other war-making items, it nested in a small park for the next five years, with "Great White Bird" painted on its noise. The plane sat derelict until 1953, when the aircraft was sold to the Biegert brothers of Shickley, Nebraska. The plane was eventually completely overhauled into flying condition and converted to an aerial sprayer and fire bomber, with civil registration N17W. It was then leased to Central Aircraft and flown out of Yakima, Washington for several years. In 1961, the plane was sold to Globe Air, which used N17W as a tanker through 1968. That was when our plane started its illustrious movie career. 006ab0faaa
