Dear Hesham!

2. Biz-jet very look like Cessna Citation

In the FLIGHT International article that hesham took the pics from (9-15 May 1990), we can read that "the design will be offered as either a nine-seat executive aircraft or a a 15-passenger commuter." So perhaps these weren't such radically different designs as you thought?
