With respect, I think people need to read the evidence about Uncommanded Flying Control Movements. A Special Flying Instruction was uncovered during the Philip Review notifying aircrew of serious and sudden changes in direction, especially after a long straight run. (Think the course alteration after Waypoint acceptance).
This was precisely what the Odiham test pilot, Sqn Ldr Burke, had experienced a number of times and reported; but MoD called him a liar. He gave evidence to Lord Philip that this SFI had not been promulgated to aircrew, and he knew nothing of it when he visited Aldergrove shortly AFTER the crash to investigate yet another occurrence. None of this was made available to the BoI. The SFI was dated AFTER the pilots underwent their "conversion" course; after which they primarily flew the Mk1.
