Mile High Orgy

Herman Crush, a Casper Milquetoast chemist, has invented the ultimate aphrodisiac, a synthetic version of the legendary Spanish Fly, in his basement lab at a cosmetic company. It is a super pheromone that turns on all the men and women exposed to it in every test at the lab. Traveling with a vial of it to corporate HQ aboard the red-eye, Herman clumsily drops it. The strong concentrate vapors permeate the airliner's ventilation system and mixes with the cabin air. In a matter of a few minutes of exposure, the mostly staid and sleepy passengers are stripping off their clothes and engaging in almost every manner of sexual activity and variation they can think of in wild and uninhibited combinations. And no extra fees are charged by the USA carrier.
