Joint Strike Fighter grounded after engine cracks found

THE Pentagon has grounded its F-35 fighter jets after discovering a crack in one of the aircraft's engines.

It has suspended all flights operated by the fleet of 51 jets while the turbine blade crack is investigated.

The fault was discovered during a routine check of one of the planes at Edwards Air Force Base in California.

It is the second time in two months the fleet has been grounded.

Pentagon spokeswoman Kyra Hawn says it is not known how long the planes will be out of service for this time.
