Apparently the AAIB have become involved but only because of the military link with the airfield.
As Rainboe has stated:
Any pilot quickly learns one cannot trust any distance perception at night. You were in the back seat of a 757 on the left, in a right hand circuit. I think it difficult to accurately assess what befell the flight until the FDR is accessed, and for the sake of the crew, a public review of what 'might have happened' is better withheld until the report over the 'incident' is released, or further positive information is officially given. It is just not fair to the crew or the airline to keep on with this speculation.
I have to agree with him and out of respect for my fellow colleagues, it is time for this thread to close until such time as there is some official news.
