Boeing’s surveillance plane – the Phantom Eye – has finished its 12-day testing at a NASA research centre in California.

The unmanned airborne system is designed to fly at 65,000 feet for up to four days and is powered by two hydrogen engines.

Phantom Eye is being prepared for its first flight later this summer.
