Built for inventor Alexander Graham Bell to test his tetrahedral structure. Much simpler triplane configuration compared with the AEA Cygnet unsuccessfully tested in 1909. Attempted test flights with the Oionus on the day of the photo saw three wheels lift off but not all four. Melting ice ended any further attempts to fly it. Photo from: Ingenium - Ken Molson Fonds
