I watched an episode on Nova last night that I don't think is new, but I had never seen it. The program was entitled, "B-29, Frozen in Time". It chronicles the efforts of a group of aviation buffs to salvage a B-29 bomber that crash-landed on the Greenland icecap in 1946. The pilot in that landing did a remarkable job and the plane was in almost perfect condition after sitting out in the open for over sixty years. The U.S. Government had given up any rights to the plane so it was available to anyone who could salvage it.
I was hoping that the PBS Video sight would have a link to the program but no luck. However, I did find that someone on YouTube put the program up in a multi-segment format. You can see the first one here and if you click through you can find the rest of the segments.
Even if you are not into old War Birds, I would highly recommend the program as a testament to the efforts of a group to achieve its goals. It's also a very interesting look into the state of aviation technology at the end of World War II. I won't tell you how the program ends but you should watch it all the way through to the finish.
Hope you enjoy.
