I didn’t say anything about those first birds, read my post again...I was talking about the current birds and I don’t recall dragging history into it...but if it satisfies you, so be it.
I’m not going to argue semantics or look at squirrels.
The U2 isnt 50 years old, those birds were built in the mid 80s and have about 80% of their airframe life left in them.
I was just replying to what you wrote.
