If your last sentence is directed at me - no, I wasn't aware that CAS (whichever one it was! ) had posted here on PPrune that the aircraft was ' off course by miles'.
As a former Hercules nav' ( I was the nav' in the second aircraft behind XV216 in the formation from Pisa ) I have little or no knowledge of Chinook operations. I have loosely followed the Chinook thread, particularly Tecumseh's input, and also feel extremely concerned that some 'Airships' were quick to blame the pilots of that fated mission.
I know that Chugalug is a former Hercules captain ( in fact we overlapped for a while on 30 Sqn. in 69/70 ) and was mildly surprised that the Pisa accident had slipped his memory. But, he, like me 'is getting on a bit ' and we don't recall everything!
