A Vietnam-era AH-1F Cobra is getting ready for display at the Don F. Pratt Museum at Fort Campbell, Ky. The work is being completed by soldiers from B Company, 96th Aviation Support Battalion, 101st Airborne Division, who say working on an aircraft that has been out of service for a while presents special challenges. "The aircraft came to us missing a lot of pieces. It came to us missing the rotor mast, main-rotor head; it was missing the weapons pylons and it only had one tail rotor. We also had to reinstall the turret and the 20mm gun," said Sgt. Steven Gould.
