Could it be read and seen that whilst he did a flypast at 100ft, he then climbed and whilst then executing a derry roll to the left came back towards the airfield whilst losing height (possibly disorientated?) and at that point when he was below 500ft entered the loop at which point he was too low?

He didn't enter the loop from 100ft from the end of the runway from what I can see?
THose are amsl figures too. Anyone know the height of the ground at various points?

The airfield is 7ft above MSL. The land north of the A27 gently rises to about 100ft. The river valley is tidal so the valley bottom is at MSL.

From the video on the day of the incident, it was clear he pulled up into the loop at around about 150 ft above the ground, and the report here would suggest that is about right from an observations perspective.

It also appeared from the initial video that it appeared too low to begin such a manoeuvre, ie to effectively enter a loop (I know there was a 90 degree turn too), but what I mean is a vertical manaouvre without a roll out before a fully vertical down component was achieved.

Just seemed it was either an incorrect manoeuvre or incorrectly executed from a point of view of the height at the entry point.
Regarding the display authorisation, at what point does a flypast element become a standard 3 cat aero manoeuvre?

Given the additional information which has come to light since the incident, and the various footage of the aircraft moments before the crash, it looks like it might be the result of the loop being
initiated below optimum height, followed by a high speed stall generated by the pilots attempts to correct the situation in the bottom part of the loop?

It still looks like he would have had enough height had he pulled a tighter second half of the loop. Unless he just thought he had more height than he did.

It wasn't a loop. Looks more like a Cuban to me.

I think it was a quarter clover.

The AAIB doc describes the aircraft pitching up into a manoeuvre with a vertical component and a roll to the left, which I read as on the way up. In a quarter clover, isn't the roll on the way down, to finish 90 degrees to the starting heading?

Interesting point, the roll did seem to be on the way up from the video.

It was, hence the "unexplained vapour" from the middle of the stbd. wing during that phase of the manouver: Probably a tip vortex from the edge of the flap.

Whether the manouvre was a Cuban / part of a cloverleaf / loop, etc, etc makes little difference. the key parts of the manouvre was the height at which it was initiated, and more importantly, the pull out at the bottom of whatever it was. IMHO the bottom part of the manouvre `looked' like a high speed stall.

laugh people do like to exhibit their superior knowledge of aerobatics on here...

Does it need a name?
It was well desrribed and videoed
The plane was inverted as it reached the top so that as it went down and pulled up it was the right way up again

Is there a book of manoevres with names?

Most aerobatic manoeuvers have proper names - a bit like in gymnastics or ice skating.

Could he actually be charged with something/jailed as a result or is it just an 'accident'?

Perhaps if he is found to have been negligent in some way.

Way, way, way too early to be even looking at this course of action.

Surely any prosecution should be for the CAA rather than conventional civil law authorities to bring?

He _could_ be charged with 11 murders.
Or he might be totally exonerated.

Perhaps it's best if the AAIB get on with it, eh?
