I heard about Anticosti, but the one I saw the pics of was up at Churchill. Larry Hearn used to show them at groundschool recurrents. I talked to some mtce guys who saw the engines. They said it was a wonder the whole ship didn't go BOOM!
It seems to me they had two fire warnings in there though--right about the time both fans went zzzziiiiiippppp-----BANG! What do you do in that case? (except turn final and land on the frozen river!)
As for the DC-4M (that was the "North Star", I believe ) "a few teething problems" might just be an understatement there! I heard a few wild stories about those multiple engine fires happening a long way from shore. The way I heard it, at least two of the engines were there based on the assumption that it wasn't unlikely that the first two would quit enroute. Great idea, but those WWII surplus fighter engines just weren't made for the long haul stuff.
