A state-of-the-art US air force F-22 plane has crashed in the southern California desert, killing the pilot.
The fate of the pilot was not immediately known after the plane, which was on a test mission, came down near Edwards Air Force Base.
The F-22 Raptor, regarded as one of the world's most sophisticated fighter jets, was on a test mission when it came down near Edwards Air Force Base.
The US air force website lists the F-22 Raptor, which is made by Lockheed Martin, as its newest fighter.
The veteran pilot was initially reported as missing, but the manufacturer, Lockheed Martin, later said he had been killed.
The air force said the jet has "better reliability and maintainability than any fighter aircraft in history".
The cause of the crash is unclear. And an investigation is under way.
The F-22 crashed at about 1000 local time (1700 GMT), officials said.

A board of officers will investigate the crash, the air force said.
But the $65bn F-22 programme has faced criticism, with opponents saying the jet is too costly and not sufficiently versatile.
The $140m (£96m), supersonic F-22 is a so-called fifth generation jet, and arguably the world's most sophisticated fighter.
The US government is committed to buying 183 F-22s, reduced from the original plan laid out in the 1980s to build 750, the Associated Press news agency reported.
It is capable of both air-to-air and ground attacks.
