B1 rolling, thats why I asked Vintage ATCO originally in this thread -it seemed as though it was a rare event!
B1 display (I use the term lightly - a couple of passes lo/hi speed with zoom climb but because of noise/speed/size combination very very impressive) restrictions have relaxed and most will end with a climb and roll. Originally a hard push over and rolling the right way out to S&L Since Mildenhall 91 (first time I saw it) the roll has been a complete 360 and still climbing. Apart from cloudbase, it also depends on how much US "brass" is around to determine how energetic the show is. There are several airshow videos that show this. Though I have never witnesseed it, a roll off the top in a B1 should be perfectly feasible and I am sure there are certain ex V bomber drivers out there who have done such a thing in their time in a Vulcan and/or Victor.
As with all "big jobs" size and speed are always gonna please the crowd and it is harder to make large objects look as though they are going fast compared to small ones. At the first UK B1 flying apearance (Mildenhall 89 I think) during the practice on the Friday, the (very) high speed pass was mis judged rather and took place at around 100' over much of Beck Row rather than 12000' of concrete.Cue several claims from greenhouse owners for smashed windows!
Wub - last SR71 flying appearance at Mildenhall was '88 - B1B didnt appear in UK untill Lakenheath show in '88 so definitely not '93!
Dutch F27 (they should do the same in a Fokker 60 nowadays)and Italian G222 always superb displays- though only the '222 actually rolls - one full aileron and 2 derrys. Italians also displayed the Piaggio 180 Avanti and this included rolls and a very viscious bunt that bordered on a stall.Dutch Troopship display ended with one of the more pronounced "Keh -Sahn" approaches - re Clophill Fete and also St Athan , were the display line is along the disused runway full of parked aircraft.
Dont think the Ukrainian Coaler actually looped - just a very tight inclined loop which keeps the wings just past the vertical. Similar to the F27, G222 and Swedish Herc- incidentally they use the oldest C130 in Europe for displays! Also I dont think he feathers 3 engines and certainly not at an IAT!- Have seen him feather outer 2 at shows abroad.
