Oh! After sloshing through the wet grass and mud to where the Europa was
parked, at a very narrow strip with BIG trees on both sides, climbing in the
plane, linining up on the runway, advancing the throttle and just as the
throttle hits the stop - the wet & muddy right foot slips off the rudder
pedal.
I thought it was "pee" factor, cause thats what I almost did!! Glad to know
that "P" factor is different!!!
