I haven't watched
12 O'Clock High (1964-1967) since I was a kid. It doesn't stream, so I bought DVDs of its 3 seasons on eBay, supposedly recorded on 21 discs for better quality. Robert Lansing was in it- I remember him from an episode of
Star Trek Assignment: Earth with Teri Garr. I hope it's good like it was 50 years ago for me...
