Well, I needed Daryl's Klaxon Friday!
Tailwheel went flat at the east end of the airport, so I got it in to the Stearman hangar area - short one-way taxiway. Walked back to my hangar, loaded a tailwheel, jack, and tools in the pickup and drove back. Passed a Comanche blocking the end - just sitting there in the taxiway.
So I unloaded the truck, jacked the tail up, pulled the bad tailwheel, then I had to pee - strolled on foot to the local pee pee place, took care of that, washed my hands (habit; they were just going to get greasy again) strolled back . . .
Put the new tailwheel on, released the jack, piled everything in the pickup, turned around and - Comanche has its engine running. Good. He will move before I have to make a big deal out of it.
Nope. He was running a 20 page after start checklist. It took two attempts to get his attention with blasts of power. So he finally taxied . . . Just far enough to block a main taxiway!
Granted, it doesn't take me long to replace a tailwheel, but strolling and peeing have become time-consuming!
