Scene, Saudi, circa 1984, or thereabouts.
Scheduled flight in the big Lockheed tri-motor to Dhahran, at just approaching sunset.
During the initial climb, both the First Officer and Flight Engineer ask if I can fly ahhh,
lower so as to assure that the sun disappears, sooner....as they were rather hungry.
Sure, says I, how about FL150?
OK with ATC so we level off at 150.
Fuel is cheap, there....then, and now.
A well fed crew is a happy crew...
