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 professor got off their seats rushed frantically to the exists in a chaotic panic.
The one lone professor that stayed put, sitting calmly in his seat, was asked: “Why did you stay put?”
He replied: “I have plenty of confidence in my students. Knowing them, I can for a fact assure you this piece of shit plane will never even start”
