Yes, I have, I recently stumbled onto this episode and another entitled "The Dart" on YouTube. Actually I have been looking for this series for decades, it is one of my earliest childhood memories. Unfortunately the only known collection is in the UCLA Film Archive and they will not make copies, rather sad because they have ALL of them. How Periscope Film got hold of these two I don't know and have been unable to contact them to discuss it. I'd especially like to see the episodes "The Snark" and "Outpost In Space" again. I suppose I'll have to settle for having "Steve Canyon" and "Men Into Space" on DVD since I'm not likely to see "Flight".
