15 seconds comes from approximating the time it would take a sound originating at 13772 feet to reach an observer on the ground. Any witness (and there are many) who reported hearing sound coincident or nearly coincident with the appearance of the fireball was describing sound generated by a prior event. Do you not agree?

Where on the ground? Some of the observers were almost 100 miles away. Again, do you have someone in particular in mind?

I agree.

Speaking to the sound thing alone, would a missile launch cause a sonic boom early in its trajectory that would give the impression the ‘bullwhip’ would be the noise generated from the impending explosion?
