Caz:
You really are a piece of work...
You just typed:-
The Chinook impacted at a Groundspeed assessed as 150 kts which is in excess of 250 ft per second. Mr Ellacott stated "I then heard the the sound of a propellor going around for about four of five seconds and then I heard an explosion. Visibility at this time was only about 9 or 10 feet maximum". He then went on to say that he did not think that he could have been more than 100 yards from the point of the explosion.
The Chinook would have been at least 1000 ft from Mr Ellacott when he first heard it
Note:- My bold...
But you originally typed:-
Just to remind you of the evidence of Mr Ellacott that the Chinook had passed over him - "I then heard the sound of a propeller going around for about 4 or 5 seconds and then I heard an explosion ....
There's a big difference between the two. Either you are confused and don't think clearly or you were being deliberately evasive. I would suggest that, in either case, your input, opinions and, dare I say it, motives regarding this issue are questionable at best.
