I ran across a phone number for the San Diego Air and Space museum today and remembered this Mutual Blackbird, so I called and talked to their curator. He was helpful , but said they didnt have any paperwork to say that Giuseppe Bellanca designed it, but that wikipedia (sp?) showed it as a Bellanca design. Not having much trust in wikipedia, I went there and went to a bunch of links and found mention of some papers from the owner of the Mutual company. In one place it referred to Giuseppe Bellanca and in another place it mentioned Frank Bellanca. This may well be a Bellanca design, just not our Mr Bellanca. Did Giuseppe have a brother? Just some interesting trivia. ____Grant.
