One more confirmation

as long as the aircraft of the same type are still in service, they will
keep the in the yard and use them for parts, until they are out-dated,
then the remains are de-milled and sold as scrap to certified scrap metal
dealers. even then, the remains are tracked until they are reduced to bits
& pieces usally by griding machines.
there are some parts that can be purchased .
some aircraft such as the F-14 MUST now be completely handled by special
demill units to insure that nothing of value can be sold except as
complete
SCRAP.

Non-combat aircraft can be sold to certified companies for reuse in some
cases.
.
some parts are available for resale, I had the name of a company that sold
them got a friend that was a B-52 gunner and he wanted a tail-gunners seat
from an early model B-52, for his rec-room. , he called them, but, no luck
so far.. he's still looking for one..

I've watched them feed several planes to the smelters. it is sad to see.

I'm told that all the F-14 aircraft are now razor blades.
That from a very reliable source.
