Claim all you want: the last B-52 with a gunner in the tail, and, thus, a tailgunner compartment, was retired in 1983. The only remaining BUFFs after that were G’s and H’s, where the gunner sat in the aft portion of the forward cockpit.
Depending on sun conditions, SOME of the blackout curtains were occasionally partially pulled, but operating at low level in an **entirely** closed cockpit was contrary to SAC Regulations, at least until I left the USAF in late 1989
Aye-Aye, Chief. Must have been a mass hallucination.....
