I wasn't a Pilot, I was Maintenance and so was TJ. I worked in the Electrical Shop and TJ was Line Shack, Plane Captain was a designation for someone who had qualified to Launch, Recover and Tow Aircraft, Launch and Recovery in this case meaning giving hand signals in coordination with Spotters to let the Pilot know when and where to turn the Aircraft out to cruise safely to the landing strip for takeoff and bring them back after a landing so they were parked and secured safely. Line Shack also fueled and defueled Aircraft, did Pre Flight walkarounds and provided the bulk of people for washing Aircraft (a big fucking job).
