AAIB
How long is a piece of string? As an avid consumer of AAIB reports for 20+ years I think we may hear quite soon, as there is so little to say. 'CFIT when dis-oriented in IMC'. There are no black boxes, no flight plans that mean anything, no radio messages of any use either. AAIB don't seem to want to see the wreckage either. Mr Sala was not happy about some aspects of the flight, but what did he know about flying?
The major interests in this one are the legal aspects of this flight and these have been examined ad nauseam here, but again this is a pilots forum and we are not legal eagles. M'learned friends are going to have a field day, but the fine detail probably will not get reported on here.
