Highest time aircraft ever...

[HA25]

Seems like most of your Boeings and Douglas's are built so well they will fly forever.
I've seen some rj's with some real wear & tear. I wonder if these aircraft will have the longevity of the old 727's, 747's, DC 8's, 9's, and 10's.

Generally speaking Boeings have a airframe life.. Douglas doesn't so in theory a DC-10 could live forever so long is you give it a D check.. I think there are some 150,000+ DC-10 out there flying around, and I know we have some here at Gemini that date back to 1971.. so you do the math. Heck, our 11's are in the high 30's..
