I have worked on several Boeing 1940's aircraft and there is a really special feeling when you see them enter into the air once again. The work necessary to get DOC back in the air was and is remarkable. B29's were very complex aircraft and to resurrect this aircraft is a great feat. Hopefully DOC will get a chance to travel around the country so many later generations can see first hand this incredible aircraft. By the way the B29 program was the most expensive U.S. military program during WWll.
