A group of engineering students and their teacher were given free air-plane tickets to go on a holiday
Once on the
plane, the captain announced that they were on the plane the students had
built. Everyone freaked and rushed out of the plane, except for the teacher who
stayed there with calm. When the flight attendant asked why he hadn't left, he
responded " I know the abilities of my students. This plane won't even
start".
