I unplugged the fixed wings heaters before i left…jerk
I had someone do that to me and to add insult to injury he used our extension cords. A one sided, loud corrective interview took place. He was not departing until the late afternoon we would have happily loaned him our equipment and plugged in his aircraft once we started in the morning. Happily our Chief Pilot was very good friends with his Chief Pilot. Call it Karma if you will but it did not end well for him.
