I would think it would be longer than that. If we have retardation at 
100,000 feet, the sound would take about 90 seconds to reach the ground 
and the meteorites at a terminal velocity of, say, 200 mph, would take 5 
minutes, so the difference might be on the order of 3.5 minutes. I'm 
sure someone will chime in with more exact figures.
