Thought it was de riguer?
Many moons ago (2004?) I watched 2 PARA doing a live firing attach up an Otterburn re-entrant supported by a pair of Harriers dropping some form of practice bombs.
The boss of 16Bde was obviously unimpressed by their accuracy and demanded that the next run impress him or else.
Cue Harrier running in inverted before verting and dropping at the last minute. I think it was the laughter of those around the bunker rather than the flying skills that silenced the Brig.
