Yes I am also aware that was 5 years ago. Because of the time span between occurrences, I am not yet prepared to conclude they are the same issue.

I am willing to take congress to task for killing the alternate engine source given this history.

The grounding was lifted today. F-35s are cleared to fly.

The funny thing is that I read it in a Australian aviation site

The listed cause of the turbine blade crack was :

"Prolonged exposure to high levels of heat and other operational stressors on this specific engine were determined to be the cause of the crack. No additional cracks were found during inspections of the remaining F-35 inventory.”

Yes, I saw them flying today. Looks like this engine may have undergone some extreme tests at Edwards which caused the crack. Apparently this is not as serious as I first may have thought.
