F-35 fighter jet fleet grounded by Pentagon
The US has grounded its entire fleet of 51 F-35 fighter jets after the discovery of a cracked engine blade.
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.
This is the latest in a series of setbacks which have delayed production and caused costs to skyrocket, as Lucas de Yong reports.
