Finally a video of the Discovery Channel Wings episode for Project Pluto! The following are parts 1 - 5 of the show.
Let me know if there any playback issues with this video provider.
There is a poor partial video on youtube as well.
There are, however, good copies of the "Nuclear Airplane" and the XB-70 episodes on Youtube proper:
I want to thank Sheldon for sending me these videos. If any readers have something interesting to share, please email me or post in the comments.
