Boeing C-97 Stratofreighter
military transport aircraft series
The Boeing C-97 Stratofreighter is a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers.
C-97s served in the Berlin Airlift, the Korean War, and the Vietnam War. Some aircraft served as flying command posts for the Strategic Air Command, while others were modified for use in Aerospace Rescue and Recovery Squadrons (ARRS).
Design and development
Design began in 1942. The C-97 Stratofreighter was developed towards the end of World War II by fitting a second lobe on top of the fuselage and wings of the B-29 Superfortress with the tail, wing, and engine layout being nearly identical.
The XC-97 and YC-97 can be distinguished from the Boeing 377 Stratocruiser and later C-97s by the shorter fin, and later ones by the flying boom and jet engines on the tanker models.
The prototype XC-97 was powered by the same 2,200 hp (1,600 kW) Wright R-3350 engines as used in the B-29. The XC-97 took off for its first flight on 9 November 1944, just after the death of Boeing president Philip G. Johnson.
On 9 January 1945, the first prototype, piloted by Major Curtin L. Reinhardt, flew from Seattle to Washington, D.C. in 6 hours 4 minutes, an average speed of 383 mph (616 km/h) with 20,000 lb (9,100 kg) of cargo. The tenth and all subsequent aircraft were fitted with the 3,500 hp (2,600 kW) Pratt & Whitney Wasp Major engines and taller fin and rudder of the B-50 Superfortress.

Why this record matters
“Boeing C-97 Stratofreighter” is worth following because a concise public description often conceals a longer documentary argument. Here, Boeing, C-97 and Stratofreighter provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 17, 2026. The linked authority identifier is Q586146. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1942, 1944 and 1945.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
