Often lay people make sense of what they have heard with words like bang, gun and rocket since their experience is limited
We should make due allowance for this in the witness comments describe above
Indeed, I was told a story by a member of the BoI into a Harrier mid-air about his going to interview an eye witness to the accident. The observer had indeed clearly seen one of the aircraft involved crash quite close to him and was able to describe the event in considerable detail. Unfortunately he was totally unaware of the "accident"!
