Ivan's B-2
Did Ivan ever get that thing in the air? I saw him try to fly it at the Arizona Jet Rally several years ago. It lumbered the whole length of the runway, hit a bump at the end, bounced into the air, then came down and ground looped.
He was using two Turbax fans, which surprised me. The airplane was so big I expected him to be using Dynamaxes or Ramtecs.
