A friend of mine worked with the Milt Caniff estate to get these once thought lost episodes restored and released on DVD (and in limited release on niche cable channels) a few years ago. The whole set is well worth getting if you have any interest at all in early cold war USAF stuff. Some of the footage (especially the zero-length launch episode Ron mentioned) seems to be higher quality than typical documentary footage of the era. Beautiful time capsule!
