F-35 ground order lifted... Sort of.
Pentagon authorities are now fairly certain that the JSF is safe to fly.
The cause of the F-35 fire on June 23rd is thought to be due to "excessive rubbing" of one of the turbine blades.
While the F-35 may be cleared for flight, its expected appearance at Farnborough is still uncertain. Until the exact cause of the fire is determined, the JSF will fly under "operating restrictions".
