KenV you make much of it not being a "missed gate", but setting the wrong gate during planning by nearly 1000ft - by not correctly factoring in the altitude of the airport - is a pretty basic mistake,
Actually, that is NOT what happened and is indeed "why conclusions can't be jumped to for this recent incident. There could be various issues to consider that are not yet apparent."
I do come back to margins however, and wonder whether they should be forced to be much higher for such "high energy pointing at the ground" type moves.
The Thunderbirds have increased the margin for this maneuver (but not all vertical maneuvers) by 1000 ft.
