Never gave this much thought, but when I had my commercial check ride in a glider, which was given by a 777 pilot, on the way back he told me to land on the grass next to the paved runway. No big deal until half way on final I noticed a tractor in the grass mowing, I shot back over the asphalt and landed as if it was supposed to be that way. He never touched the controls, but he never said a word until we stopped on a taxiway. He got out, walked back to the hanger and when I got there he had my signed ticket, shook my hand, said thank you and walked to his car! I figured he was ok with it! :highly_amused:
