The latest update on the B-29 "Doc" is that they now have all four engines on hand and they hope to run them up in May. It went on further to say they hope for Doc's first public appearance to be at Airventure in 2014! It will be so incredible to see a second 29 back in the air. unfortunately they said FIFI has another commitment during that time so they won't be together yet, however they are definitely planning on getting them both together in the air as soon as they can. That will be a truly historic event to have two 29's together in the air! I hope I can see it in person when it happens.
