Not sure if this is the proper place for this, but here goes.
When I was in college, I worked a summer as a ramp rat for a local flying service. Late one afternoon, a local came in and parked on the far side of the ramp in his Push Pull (337). He came in the office and asked me to top him off. I guess he was in a hurry or just did not want to get caught in the weather that was moving in fast from the northwest. I got in the tender and drove across to where he parked. I did not want to get caught in the weather either so I was in a hurry and made a really bad mistake. I failed to hook the static line to the nose gear. I was up on the wing with the nozzle locked wide open when lightning struck off the end of the runway. I felt some static in the nozzle and almost fell off the wing. Fortunately, the nozzle did not come out and I did not spill a drop. More fortunately, there was no ignition/fire/explosion/death. I grabbed the rubber part of the hose and finished as quickly as I could, got down and put the tender up. I vowed never to fuel another aircraft without the static line attached and to try to avoid using the tender at all costs. Guess someone was looking out for me that day.
