I nearly posted this on the illustrious (pun intended) Sea Jet thread. It just goes to show that you should not burn your bridges too early!! Or count your chickens etc......

First flight of the first short take-off and landing (STOVL) Lockheed Martin F-35 Joint Strike Fighter, BF-1, could be delayed following a repeat of the Pratt & Whitney F135 engine turbine blade failure that led to a hold up in flight tests last year of the conventional take-off and landing (CTOL) JSF.
The failure of the low pressure (LP) turbine blade is thought to have occurred in engine six which was undergoing flight clearance "proof test" ground runs prior to installation in the first STOVL F-35, BF-1. The tests were aimed at proving, on an engine-by-engine basis, that the specific unit was safe to use in BF-1, and that it did not exhibit the same combination of assembly characteristics, tolerances and other factors that led to a similar failure on a test stand engine on August 30.' - From AWST, Guy Norris.
