The older airframes seem generally more dependable. They don’t make ‘em like they useta!
I don’t know about that. There are a lot of ‘bent & cracked’ airframes that are red lined below their designed g-limits (among those older aircraft). That’s why the USAF is buying more F-15’s to replace the old F-15C’s. It’s an affordable stopgap solution to keep the available airframes from cratering.
