Nope, loud sounds travel as fast as quiet ones, unless there's a shock wave, which can exceed the speed of sound. But once it's no longer a shock wave, it's just ordinary sound and travels at sound speed. True, HE bombs make shock waves, but they dissipate in tiny fractions of a second and can't be used to explain an 8 sec. delay. It takes a large nuclear weapon to support a shock wave that continues to exist 8 seconds after detonation.
I noticed you sent him a crafty message here a year ago but he never showed up.
