Video recording information for LS#2:
The storm was upon both Flash and Boom when the second lightning bolt hit. The direction to the strike could not be made out clearly in either video recording, except that it was more to the West than East of Flash. However, the delay between the flash of light and the thunder clap was accurately measured. The delay was 7.943 seconds on Flash’s recording and 15.749 seconds on Boom’s.
