F-1 thrust sctructure

This is the thrust structure of the F-1 engine outside the New Mexico Museum of Space History. The engine produced 1.5 million pounds of thrust and had to transmit that thrust into the Saturn V rocket above it. The F-1 was also gimbaled, so that the thrust could be aimed to steer the vehicle as it flew into space. This image was taken at 18mm focal length with and exposure of 1/800 seconds at f/3.5, ISO 1600.
