Yeah, near a major river, we get all sorts of bangs, crashes, and booms -- no way to anticipate them for recording. The one exception was the blowing of the levee at Birds Point, MO. I watched the explosion on TV, then realized I had time to walk outside and wait for the "BOOOOOOOOMMMM", then called a friend in time for him to run out and hear it. Most impressive. But I don't know of any recording except the TV stations' crews at Birds Point.
It’s like that Chem plant explosion in China or the Beirut blast, people recording video were surprised when the sound and blast wave hit some moments after the BOOM.
Believe the sound blast travels at 1000 ft per second. Light goes at 186,000 mps, so you so the blast almost instantaneously, but the sound has to catch up.
