Trouble with the F-35 fighter jet’s front landing gear has re-emerged, leading on Wednesday to an unseemly incident that left one aircraft looking a little bit glum.

As the F-35A was forced to land after an unspecified midair emergency, the front landing gear collapsed, leaving the jet face-down on the runway, Defense News reported.

Local media were able to capture a photo of the situation:

F-35s have had issues with front landing gear in the past, with US Navy pilots complaining last year that the aircraft would bob up and down when being launched from carriers. The issue was so bad that pilots said they could not read instruments and they experienced pain from the movement.

The US Air Force has launched an investigation into Wednesday’s mishap.
