I've heard rumours that a 767 once operated into JER empty as training
I believe a Britannia 767-200 operated into the Island in the early 1990s, which must have been quite some sight
I’m not sure if I’m correct with this one, it could have been a different aircraft, but I also seem to remember that BA brought the 767 down for a training flight around 01/02 (although it didn't land).
