'Barisal guns' commonly heard in Devon and Cornwall for over 2 hundred years (used to blame Concorde but they can't now can they.)
Last one recorded on 18 Oct 2012. Seismic reports confirmed a loud bang; no military aircraft in the area at the time.
Another similar one on 26 Oct 2006 discussed in this forum from that date. This time possibly attributable to FAF Rafales on exercise.
