A bowling ball dropped from a 6th storey building has a fairly vertical
component to its trajectory. Whereas, a practice bomb dropped at
low level would have a much higher horizontal vector.


I'm only guessing, if the plane was over a backyard, it was possibly on
finals or in the pattern at the very least. At a forward speed of 200
kt, the forward momentum would (possibly) make the bomb bounce out of the
hole at a 30 degree angle. The 'foot deep' crater could then also
be described as a 'foot deep' skidmark. It would help if we knew
how long the crater was ;-)


That's only an opinion, your mileage may vary.
