A stuck valve leads to an impromptu skydiving flight

“You gotta let me pay you for your time and materials,” I said to Art and Goren (not their real names), the two ag pilots who showed us how to free up a stuck valve on the 0-200 Continental engine of our Cessna 150. They simply refused payment of any kind. Then Art said, “Well, I would like to jump from a 150.” Jump, like parachute jump? That is exactly what he meant.
