Bell Oionus I

The Oionus I had its origins in March 1909 with the dissolution of the AEA, when Alexander Graham Bell hired both Frederick W. "Casey" Baldwin as an engineer and J.A.D.

The internal structure was based on tubular-steel with linen-covered wings and interior sections; a four-wheel chassis or running gear formed the undercarriage.

After construction was complete in February 1910, and a new engine was installed, McCurdy readied the aircraft for flight, taking it out on some ground runs.

Ballast was added to the tail and on 25 March 1910, a test flight off the ice at Baddeck Bay succeeded in three of the four wheels coming off the ground.

McCurdy ended the flight in order for modification to be made for future testing, including adding more incidence to the wings.
