Images from the feature length first episode of the 1979 TV movie Buck Rogers in the 25th Century. Interestingly, for 37 odd episodes, I don't recall a lot of space suit action.
This is Buck wearing the suit they found him in although it appears to lack a space helmet. Even more interesting is the fact that the suits is on loan from the prop store and has a long history through film and TV, starting in (1959) Men into Space and continuing all the way to Laverne and Shirley (1982)and possibly beyond. Follow the "Men into Space Helmets" thread to view the history of its appearances in company with a particular space helmet.
A big thanks to blog follower Tim for bringing this latest appearance to my attention.
