Sorry for the thread drift, but I was told the the Beverley had an oil consumption of 20 gph!
I was a passenger in a Beverley trainer out of Singapore up to Okinawa and Hong Kong way back in the early 60s, when I was flying helicopters in Malaya, and somewhere over a lot of water they shut down both engines on port side. Engineer disappeared into the wing, emerged after some time, and I'm sure some loss of height, before crew unfeathered and restarted both and we continued happily on our way. I gathered it was to top up oil ... is this feasible? Whatever, I was well impressed.
