This wasn't the only case of an Allied aircraft being delivered to (what amounted to) 'the other side'. A Spitfire pilot, (I believe he was an American serving with the RAF) diverted to a Vichy French aerodrome in North Africa on his way to Malta, either from Gibraltar or from an aircraft carrier (probably a carrier - could a Spit, even with saddle tanks and on max lean, make it from Gib. to Malta?).
I seem to recall reading that he was not prosecuted after the war, (possibly because he was American and not British or Commonwealth?) which surprised me.
Does anyone have the full story about that incident? From what I've been told of conditions on Malta during the siege, some might say they could hardly blame him not wanting to go there!!
Not the same thing, but there were said to be whole squadrons of B17s and other types parked on Swedish (and Swiss?) airfields towards the end of the war.
