Here is a little story I read of in the book "The Last Escaper."
In April of 1940 twenty four Hampdens were out over the North Sea in daylight, looking for some reported German ships. They were set upon by BF-109's and six were shot down. Only one of the Hampdens hit was able to crash land on an island off the Norweigan bearing a dead rear gunner and a badly burnt wireless operator and a injured navigator. They wounded were being treated by a Norweigan doctor when they heard that one of the 109's had run low on fuel and had to make an emergency landing on the island. Aided by the doctor, the three RAF men were taken to the 109, where they removed the seat and canopy, but the wireless operator in the rear fuselage, and had the pilot, Don Domaldson, sit in the navigator's lap. They refueled the 109 with car gas and tried to take off, but the combined weight of the thee airmen, combined with the low octane rating of the car gas, led to their being unable to make a successful short field takeoff. On the third try they hit a tree and that was bloody well that.
Don Donaldson later was one of the few to eventually escape from a German POW camp and return to Great Britian, sneaking aboard a ship bound for Sweden.
Three in 109! Imagine that flight over the North Sea, with two guys in the cockpit. Sounds a wee bit breezy.
