I found a website which claimed that 3500 feet of 35mm film was shooting at a maximum speed of 10600000 frames per second, to catch the first millionths of a second after the trinity explosion. I have an issue with how in the world this was done. I know that the camera exploded and the film had to be contained, but 10600000 frames per second means it traversed ~37mm 10600000 times every second. This means that the film spool must have been traveling at 894,000 mph! This would have run through the 3500 feet of spool in .0027 seconds! Am I doing these calculations wrong, or is the website wrong, or is the "huge spool of pre-tensioned 35 mm film" not quite as I am envisioning it?
