I grounded a Goofy a few years back after being involved in the destruction of not one, but two different airplanes. I should have known better!! Besides have you ever noticed how almost all of these cartoon guys only have three fingers and a thumb on each hand...I dont think they can get a good grip on the stick with that sort of handicap..
I do have Buzz Lightyear jumping from my Aerostar 40 on a regular basis...no harm there, If on those rare occasions when he forgets to open the shute he only hurts himself
