(NEW YORK) -- For the third time in less than a week, a United Airlines Boeing 787 Dreamliner had to make an unscheduled landing because of a mechanical issue on board.
United flight 94 was on its way to Denver from Houston on Sunday when pilots got an indicator in the cockpit of a problem with the plane's brakes.
The 787 returned to Houston, making an emergency landing there since pilots apparently did not know how well the plane would stop on the runway.
The Dreamliner landed safely.
