Thanks fantome, I'd forgotten that Duke Elegant episode.
I had a real good friend who lived in Mill Village NS, not far from Yarmouth, who knew about that flight. Alf was a private pilot who had been with Ferry Command during WW2. He was also a lover of anything from the ocean, particularly shellfish. His reaction to ditching the lobsters, which I think I passed on to the the Duke, was ''They should have thrown the co-pilot overboard and saved the lobsters."
