Gulfstream Commander 900

Gulfstream American Commander Division announced it will build a lower-powered version of its large-cabin 1000 model. The new airplane will be called the Commander 900. By moving the floor and the pressure bulkhead and by changing the windows, Gulfstream has been able to come up with a great deal more cabin space inside the old Commander fuselage.
