Aero Commander 1121 Jet Commander
The Aero Commander 1121 Jet Commander was one of the first small business jets built in the United States. Its programme was bought by Israel Aircraft Industries, which developed it into the Westwind family. The original aircraft had a distinctive straight-wing, rear-engine layout and was marketed before the business-jet market had fully matured. Only a small number were delivered before the transfer to Israel, making the Jet Commander much rarer than its Westwind descendants.

This straight-wing, rear-engine Jet Commander predates the Westwind family it became after Israel Aircraft Industries bought the programme.
