As airliners have grown bigger, so have the jet engines needed to thrust them into the air. We're now at the point where the words “jet engine” conjure up something with a maw big enough for a Mini Cooper to easily drive through. But not every jet aircraft is a double decker people carrier and not every engine is a behemoth.
