How old is the oldest B-52 still in service with the USAF?

Thanks.

Nice Question, someone of the ppl actually working with the leftover rest of them will have to answer it.

In general, the B-52's longevity is marked by the fact that in at least one family of airmen, the grandfather, father, and son have all served as B-52 crew.

008 was the one that flew longest up to 2004, with less hours than any other airframe in the family, but a total of 49 yrs (from JUNE 11, 1955).

There will probably be older ones, if you look at the service hours estimated for distinct parts, setting a min of 30.000+ hrs of service life = 80 yrs at current usage rate):

Now THAT is a very successful design.
