Just to throw some more fuel on the speculation fire.
I remember as a young lad overhearing my father who was RAAF aircrew talking to my Godfather. Hearing them discussing how my godfather was told he was going on a one way mission in a Canberra to Indon. "Yeah, I was told I was going to take off, fly there in accordance with the Nav's directions, drop our bombs and get as far back to the coast of Oz before we ran out of fuel, they would pick us up by boat, thank heavens it was called off"
Not sure what period of time they were specifically talking about. Unfortunately, they have both long slipped the surly bonds of the earth.
