Chinook
Ark Royal. Entirely agree your "Why the chinook continued more or less straight into the Mull, instead of turning left to follow the coast below the cloud will never be known without doubt." Forget about assumed tracks and so on, but can we also agree that if the a/c had been about 500 yds to the left, (confusion between lighthouse compound and fog signal compound?- just a theory) it would have cleared the hill ahead with around 200 ft to spare, and no-one would then ever have known about this most greivous breach of airmanship ie flying blind over hills. With all good wishes JP
