Anybody who’s ever boarded an airplane knows that there is something terribly inefficient about the slow, agonizing process. Astrophysicist Jason Steffen decided to do something about the messy procedure, using science to develop a plane boarding method that cuts seating times in half.

The idea is simple enough — passengers with children still board first, but then passengers whose seats are each separated by a few rows enter in quick groups of three, which is when the magic happens. When they test his method with a real plane, people sat down in almost perfect synchronicity and the process was quick and painless.

Steffan invented this technique in 2008, but for some strange reason no airline has adopted it.
