Lockheed 9 Orion
Designed and tested in 1930-31, the Orion was the last aircraft built by Lockheed to feature all-wooden construction. The Orion was a single-engine, single-pilot, six-seat passenger plane designed to meet the growing need for commercial light aircraft. Beginning in May 1931, it was adopted by thirteen U.S. airlines, and enjoyed a good reputation for speed and reliability. Unfortunately, in 1934, the Civil Aeronautics Authority passed a requirement that all commercial aircraft feature dual engines and a copilot for safety, and the Orion became obsolete. It continued to be used by private carriers for cargo and mail delivery, and 13 aircraft were supplied to the Spanish Republican air force during the Spanish Civil war. None of these planes survived the war. In fact, of the 35 Orions built, only one example remains in a museum in Switzerland.
The plane had a historical range of 720 miles. The plane uses 20.5 gallons of aviation fuel per hour at routine usage. A full load of fuel costs $24.40.
