So what I wrote in the first place is correct.

Of course I would not necessarily believe lockmart that the titanium "is
working" as the program has a history of hiding deficiencies. Those
deficiencies covered up include these same tail cracks, which wa a story
broken by Reuters 6 months after the delamination was discovered.

The only way to know if the third attempt to fix the F-22's tail is to fly
the airplane 500 hours.
