Can I add my 2 cents worth, too?
All you have to do in IMC form is hang in there, maybe slide in a little tighter and it's no problem. You can still see the guy and it's certainly a good reason to try a little harder to maintain station...
There ARE procedures to follow if you lose your grip on the other guy or your nerve.
The Briquettes are allowed to fly towards the crowd (where others are not) because they don't do any of the really tricky stuff the major teams like Blue Angels do, like opposing solos and other fancy ****e like that. Or that thing the Frickin Tricolore were doing at Ramstein that didn't quite work out.
Not much to go wrong in long, boring formation passes with loose spacing.
