A similar thing happened to me while flying around for about 1.5, on half tanks in a 152. I parked the plane but upon going to twist the gas cap off to fill it up, found that there was not one to be found. Talk about a chill going down your spine, you're basically just standing there trying to figure out how you could possibly make the mistake after preflighting an airplane hundreds of times before. Lucky I didn't pull too many negative Gs so there was still gas in the plane, but sheesh, it was an awful feeling, had no one to blame but myself too. The cap was later found in the grass by the piano keys with it's chain still attached. Apparently I lost it turning from the taxiway onto the runway. Live and learn, live and learn.
