Another North Atlantic Baron story.
707 crew arrived in Anchorage, and the Captain asked if, instead of one of the routine crew menu/meals the following day, he could have a round of Roast Beef sandwiches instead, on Rye bread ? The Alaskan, or indeed any U.S. State, "sandwich" being a little more than the miserable curly cornered little "sandwich" that one remembers as a sandwich in the UK. No problem, said the Stn.Staff.
On departure day the Duty Officer attended to the departure, got the Load Sheet signed, doors closed, watched chocks away and went back to her office to complete the paperwork.
Not long afterwards she received a call from the Control Tower asking what was the problem with the Speedbird 851 ? Nothing, she said, I despatched it about 15 mins ago, well said the Tower, it's still here. Finding a vehicle the D.O. drove out to the aircraft, plugged in a headset and asked what the problem was. I haven't got my roast beef sandwiches on Rye, said the Captain.
He got them ( that's why they call it Contingency Fuel )
N.Atl.B's could do that.
