A group of Engineering professors were invited to fly in a plane.
Right after they were comfortably seated, they were informed the plane was built by their students.
All but one got off their seats and headed frantically to the exits in maniacal panic.
The one lone professor that stayed put, calmly in his seat, was asked: “Why did you stay put?”
“I have plenty of confidence in my students. Knowing them, I for a fact can assure you this piece of shit plane will never even start”
