Fermilab's Jason Steffen became so frustrated over the delays
in boarding an aircraft that he decide to do something about
it. He has applied a computational technique commonly used to
map the movement of atoms and molecules to simulate how
passengers move around a gridded space on an aircraft.
According to his research the most common way airlines use to
board passengers on an aircraft is mathematically, an extremely
inefficient technique. Instead he suggests applying a strictly
ordered optimal sequence that cuts boarding times by a factor
of 7.
