There is an old Monty Python skit where John Cleese and Graham Chapman play airplane pilots. Presumably on a long, tedious flight, they are clearly bored and keen on amusing themselves at the expense of their passengers.
They find entertainment through relaying worrisome, nonsensical messages. Cleese begins their prank with the truism, “Hello, this is your captain speaking. There is absolutely no cause for alarm.” And after some internal discussion about what there should be no cause for alarm about, they add: “The wings are not on fire.” The messages get more ridiculous, and hilarity (at least for the pilots) ensues.
While fictional pilots can pass the time during long flights by pranking their passengers, real pilots have to find other ways to stay awake. Unless, of course, you happen to be a great frigatebird, in which case you can just sleep on the wing, as a paper published in Nature Communications this August reported. (more…)
