I see you chose your name carefully
Why should the Chinook crew attend an enquiry into an accident in which they played no part? They are probably in Iraq or Afganistan so unable to attend anyway!
"Are you suggesting that if there were fast traffic in the area they would definately be maintaining under 500' AGL."
Yes that is what they train for and do very well.
"Therefor FJ traffic could well have been in the area without nay record"
No they couldn't - they have to book into and out of Low flying areas and none were booked into that area at that time - see AIB report
Your comments about the Tornado GR4 are correct is has TFR but if any jet was using this they would definitely be at 250ft or below.
You seem to be unable to accept that this has all the hallmarks of inadvertant entry into cloud followed by disorientation and a tragic loss of life. The GPS info though not perfect seems to prove this the theory of UFIT.
