The manoevre has been called a loop, and for that we can calculate a safety gate. The final manoevre was more akin to a barrel roll (p10-as the aircraft approached the vertical it began a LH roll). Maybe because the speed was lower that needed for a full loop, but no surprise that only 2700ft was achieved. The aircraft exited the manoevre 60deg off hdg, so perhaps AH accepted the lower altitude as he knew it was not a complete loop and intended to continue rolling, as he did and ended up rolling out off his planned track. Safety gates for barrel rolls are somewhat more fluid than loops.
