Not sure about the plane....thought it was Osprey since described plane is similar. Osprey has been in development for more than 20 years, costing more than 30 Billion (in 1988)...don’t know about costs since.

Osprey began production in 2005.
The Ospry crews are in their final training, prior to being assigned to Iraq.
