A transatlantic United Airlines Boeing 787-8 Dreamliner was forced to return to the airport just moments after taking off after suffering a mid-air engine failure.

Flight UA108, carrying 219 passengers and 11 crew members, departed Washington Dulles Airport at 5:40 p.m. on Friday, July 25, bound for Munich in Germany.

But as the jet climbed through 5,000 feet, the left engine failed, prompting the pilots to declare a 'MAYDAY' and alert air traffic controllers.

What followed was nearly three hours of tense aerial maneuvering.

The crew entered a holding pattern northwest of Dulles, circling at 6,000 feet while dumping fuel to reduce the aircraft's landing weight.
