A few summers ago I was aerotowing gliders in a Pawnee. On the umpteenth tow, just as we were passing the upwind boundary a
ing great wasp appeared under my nostrils - and I am allergic to wasp stings big time!
Fortunately the experienced glider pilot behind me managed tp stay with my gyrations as I swatted the b@stard away from my face a few times before I managed to open the fresh air scoop above my head and blow it down the back of the fuselage.
