43. 757 refuelled right wing, 767 left wing.
Well go and look on a BA 767 right wing, and you will find A SECOND refuel panel.
The story is that when they bought the aircraft, one of the options was refuelling from right wing as well as left. The guy that ticked this box thought he was buying a second set of refuel couplings. He got a complete refuel panel. (If both are open the left one takes priority)
