Engineering Professors

Ten engineering professors board a plane. Once they're inside and the plane is a about to take off, the flight attendant comes out and tells everyone that the plane has been built by the students of those teachers. Immediately nine of the professors get up and run away from the plane while one of them stays sitting, calmly reading a book.
One of the students who was on the plane to gather performance data approached the professor, thanking him for trusting them.
To which he replied, "If my students really made this plane I'm 100% confident it will never take off."
