The Berlin Airlift Historical Foundation’s Boeing C-97 flies again. Amazing to see all four P&W R-4360 engines and their collective 112 cylinders moving this magnificent machine through the air.

The Boeing C-97 Stratofreighter was Boeing’s last piston-powered design and implemented as the Boeing 377 Stratocruiser airliner, it was the end of an era as jets became the wave of the future.
