"There's been a lot of speculation about the aircraft and that Cessna might
introduce the plane at next week's Aircraft Owners and Pilots Association
Summit in Long Beach, Calif.
"But that's not the case, said Cessna spokesman Bob Stangarone.
"'What we're flying is not a prototype or proof-of-concept aircraft,'
Stangarone said. 'It's a technology demonstrator to help us determine how
best to fill the gap between the Corvalis and the Citation Mustang.'
"Any new aircraft introduction would be "some time away," Stangarone said. | c**i
