Well….maybe.
There is no evidence (apart from circumstantial) that the Dornier is the one they say it is. Certainly, a Dornier 17 did come down on the Goodwins on 26 August 1940. There are no crew unaccounted for on that particular aircraft.
However, there were plenty of other Do17s in that sea area.
RAFM have been saying for a while that it is that aircraft (I think they have recently changed that to ‘believed to be’) but there is no firm evidence. As far as we know, no positive I/d yet, either.
However, for the purposes of a licence to be granted under the PMR Act the aircraft needed to have no bombs or bodies on board. The aircraft in question ticked those boxes.
