Fly, then fix. Much cheaper.

p51 is a bus compared to an f22.
its not banging aluminium togther anymore. it took years to learn how to work with the various engineered materials
and how to assure quality in those huge center fuselage
structures which if not cured along a specific temp/pressure
curve will fail QC. the planes fly at the edge of stability
with huge loadings. also all that software needs constant ginning up to meet new threat profiles. they are hugely labor and capital intensive for a reason.
“Fly, then fix. Much cheaper.”
uh...not if you’re a spacecraft....
