I don't have the answer to your question. However, could I ask what your agenda / gripe is with SF? The reason I ask is that you posed a similar question on the recent Herc thread (now locked). Now it may just be me adding 2 and 2 to get 5 (I am a fully paid up member of SODCAT after all!) but are you trying to infer that the only reason the Chinook (and the Herc for that matter) was at low level was because it was planned and/or flown by an SF crew? If your answer is no could you enlighten me on your agenda / thoughts behind the question?
