I am disappointed in what you have written about vibration levels at speed - the Mk2 was appreciably better and indeed it was said that ZD576 had been at speeds of over 140 kts airspeed earlier on that fateful day and it had been fine.
You all seem to be forgetting that the windspeed increased significantly over the landmass and that analysis does not have the airspeed having to have been excessive for the (high) ground speed to have been realised.
All that is known about speed, track, engine state, a/c attitude, etc is consistent with them having been surprised at their immediate proximity to the ground and the a/c very much flew straight in apart from the apparent attempt to initiate a "quick stop" in the last seconds.
I have suggested a scenario which may account for them confidently approaching as they did but apparently that the equipment concerned is still considered rather “OPSEC” is enough for you all to put your blinkers on.
There is nothing greater in terms of national security than getting to the bottom of what happened that day if it is at all possible to do so – we have not exhausted all opportunity of getting to the truth if we ignore the possibility of the use of this equipment.
If you have any input but are (quite understandably) concerned about breaking security regulations or jeopardising your career, why not explore some way of getting your input directly into the inquiry confidentially – there must be a way.
You do not have to subscribe to any “conspiracy theory” but those running the inquiry need to have available a whole picture of the systems available to the pilots and their practical use – as this has thus far not been volunteered by the establishment (MOD/RAF), it can only come from individual aircrew who have a different kind of courage.
