i went to an airshow a few years ago, my grandpa was the mechanic for the last flying b29 (fifi) and a warthog did a low pass over the airport (only a few hundred feet) we were at in midland odesa texas. was loud enough it shook all the hangars, i dont think i wanna hear a sonic boom. the crazy thing was the pyrotechnics they use, that was loud and makes a LOT of heat (i know completely random)
