From the article: "This is 1/100,000,000th of a second after the first photo."

A 100 millionth of a light-second is about 10 feet, the tower was 100 feet. So that couldn't have been the time between exposures, and they used multiple cameras anyway.

The Wikipedia article https://en.wikipedia.org/wiki/Rapatronic_camera says the exposure times were several microseconds.

I don't think that's the first image in the sequence, just the most famous one. They took a lot of images in sequence. Here they are edited together into a sequence (several series, presumably from multiple tests, unfortunately looks a bit incomplete): https://m.youtube.com/watch?v=KQp1ox-SdRI
