Bring on the Banjo!
Aldergrove's 202 Sqn Met Flight crews aboard the Hastings for 8-10 hour flights out into the Atlantic dined on Banjo Rolls. The name came from the banjo union, a circular fitting used for components such as petrol feed to carburettors or oil drains from motorcycle valve gear.
The crew took it in turns to fry bacon and eggs for insertion into a round bread loaf, known in Northern Ireland as a bap. Two captains used their rank to demand the fat from the pan poured over the delicacy, thereby boosting their cholesterol levels to undreamed-of heights, had they only known about such things. My father complained that the cockpit often became a greasy mess and had to be wiped down with petrol.
