A giant of the skyways poises for flight, Langley Field, Va. The four powerful engines of a YB-17 bomber are warmed up before a takeoff (LOC)

    While we see only three of the four ostensibly warmed-up engines, it is clear that at least one of them - starboard inboard - isn't running at all... :) Looks like an A-20 in the background on the right - not sure what is in the background on the left - a Ventura perhaps?

    Hi, I'm an admin for a group called B-17 Flying Fortress, and we'd love to have your photo added to the group.

    Interesting shot, I never realised that any YB17's remained in service during the war years. Interesting to see that nose turret arrangement. The aircraft to the left is a Douglas B18 Bolo, a bomber based on the DC-2 transport aircraft. The B17 and B18 were designed to the same specification, so it's interesting to see the two in the same shot.

    Was it really still being called the YB-17 in 1942?
  • Szmytke said:
    It would be specific to the aircraft in this pic which is a Y1B-17, identifiable by the visible lack of armament, bubble blister in the nose glazing, no dorsal or ventral turrets. It could be a 17or 17B , the only difference is turbochargers, so I suspect this is an non turbocharged aircraft
  • Szmytke said:
    Twelve Y1B-17 were delivered between January and August 1937, equiping the USAAC's 2nd Bombardment Group at Langley Field, Virginia. The 13th test bed model was redesignated Y1B-17A and provided with GR-1820-51 engines with General Electric turbocharger (supercharger powered by a turbine driven by exhaust gas). It flew for the first time on 29 April 1938 and subsequent testing gave proof of the superiority of the supercharged engine over normally aspirated ones and such engines were to become standard. The YB-17's were designated B-17 by the 2nd Bombardment group at this point. There was great political tension between the Army and the Navy at this point after the interception of the Italian liner "Rex" which goes a long way to explaining why the USAAC had only 30 on the books when war broke out in Europe. The order for Y1B-17 was followed by a contract for 39 B-17B's (same as the turbocharged Y1B-17A) which were all delivered by March 1940. The B-17C, with uprated R-1820-65 engines and an increase from 5 to 7 guns were first ordered in 1939, and the first of 38 models flew in July 1940.
