A couple of weeks ago an A400 was doing the same in the Eddystone Lighthouse area, in between some circuits at Jersey and Guernsey and (if I recall) a few at Newquay - or perhaps I should say St Mawgan.
Regarding jumping from aircraft sans parachute, Brian Lecomber used to jump from the wing of a low and slow Tiger Moth as part of a barnstorming act around 1970. Probably his small stature aided his survival though I believe he did break the odd appendage despite a well padded suit - padded cell might have been more suitable.
