I too was on the 'air to air' flight, was treated to lots of power changes, slat popping, banks climbs, dives and spoiler activations-wonderful stuff. Until I saw the Beech alongside us, I had no idea what we were up to, I just assumed it was a wild ride for us enthusiasts!
Someone on board told me we were in 'Military Airspace', and after getting home that night I was sent this by a friend of mine who plotted the flight-I cant vouch for its accuracy, but it seems to fit pretty much what we did?!
