The next challenge is ready and waiting for Asturias56 to fire the starting gun...
Not one I can se on the list of previous and hopefully compliant with the spirit and rules of this contest.
A photo I took myself, but I'd be amazed (and delighted) if the super-sleuths on here didn't crack it in double quick time.
The link to the DC-4 made for interesting reading. Never been to the FI myself but used to fly with one of the original FIGAS pilots, whose obituary in the Telegraph in 2005 told of a "mercy" flight he'd undertaken for a sick child in a Beaver IIRC. A marvelous piece of flying.
