Can we just put to bed the fallacy that he was 'too low' entering the manoeuvre. This was, and still is, perfectly acceptable. It was explained again by LOMCEVAK and is common practice in both civ and mil displays.

Obviously, if you pull up lower you need more speed to make the same apex height and airspeed.
