Can't find an image that supports the Brit theory though...
I'm as sure as I can be at 50 years distance that it was a jet airliner. Just to dribble a little bit more info in, the types flying charters to Greece at that time would have been 1-11, Comet 4x, and 727. The idea it's a tailplane wouldn't work for 1-11 and 727 which were T types, but I think might for Comet 4, interesting idea.
