Here are the two giant cameras, one facing forward and one back to create huge panoramic pictures with details on objects as small as two feet across. Amazing for the time and that these were physical cameras, taking snapshots onto film. hard to imagine in today's digital world, but back then it was cutting edge. The silver balls had helium in them to aid the film train. The film was moving very fast and was very thin so the helium helped keep it light and moving without snapping. An extra precaution because if that happened, there was no fixing it.
