And if a lot of those hours are spent on long missions and relatively
few take-offs and landings, that stresses the airframe less.

I seriously doubt that this one ever gets anywhere in the neighborhood
of its max gross weight of 488,000 pounds as a research launch
vehicle. Yes, lighter weight does significantly reduce stresses on it.
74 of the H models, like this one, are in active service by USAF; 18
were sent to desert storage at Davis-Monthan, AZ, about a year ago,
and can be easily and quickly put back into active service.
When I was in H's in '71-75, they had only about 5k hours on them,
including Chrome Domes (airborne alert missions); now, I think they
have about 15k hours - still very "young" airframes when you consider
that many Boeing airliners have 75k hours and more on them. That's
why USAF can plan to use them for another 40 years.

Wow.
I wonder if it (as a launch vehicle) ever carries its rated load
capacity? (would that lessen airframe stresses?)
I'd expect that the ones that got heavier use (ie chrome dome) would
be beer cans by now... (kinda like the earlier variants of the sky
pigs...)
But they sure have built it well!

That's pretty cool. But the idea of a 40+ year old airplane still
doing useful work like that is encouraging and disturbing at the
same time...

BTW, just checked my Form 5 (flight records); I flew this launch

We have changed flights and will be coming over sooner than
expected ;-) although the landing might be a tad rough =-O
