What the human brain thinks it hears in an explosion is significantly delayed from what actually happens. Even area mikes get clipped and discerning a frequency content is almost impossible if the source is close.
If however the explosion is in the back of the plane the mikes might have a chance at detecting the arrival of multiple airborne and structural waves arriving at different times. Of course it still needs to be recorded and that's iffy as well. In other major explosive events most of the signature was electrical ringing as the wires were cut.
