F-35 Grounded After Engine Blade Crack Discovery (VIDEO)

The US has grounded its entire fleet of 51 F-35 fighter jets after the discovery of a cracked. The fault was detected during a routine inspection of an air force version of the jet (F-35A) at Edwards Air Force Base in California, said the Pentagon.

Different versions are flown by the navy and the marine corps. All have been grounded.

The F-35 is the Pentagon’s most expensive weapons programme with a cost of nearly $400bn (£260bn).

The Pentagon said flight operations would remain suspended until the root cause is established.

Friday’s order was the second time in two months planes from the F-35 range have been grounded.
