I have seen that look on a person’s face before when the FSDO calls right after they return form a flight. We had an issue not too long ago in the Detroit area where a school was paint balled and toilet papered from the air. Turns out it was a kid who not only just got his license, but also was about to graduate and receive a full scholarship. If i remember correctly the license:suspended, graduate with class: didn’t, and scholarship: gone. All that for a little practical joke.
