Depends on the series year. The last season, it was being shut down, and it showed.
One of the "other" (LPUHF seeking to glom on to local cable systems.) channels ran it about decade ago. Buster Crabbe had a cameo. Jamie Lee Curtis was in an epi or two. Some others paying their dues.
Check out this ridiculous video someone made as a humorous tribute to it (Buck Rogers in the 25th Century). Yes, it is actually the same clip over and over for 49 mins, 20 secs. Be sure you have your audio on.
They titled it: BIDI BIDI BIDI BIDI BOOTY BOOTY BOOTY
