The Aircraft

 
The first aircraft in our collection is a DC-7B (N836D) serial number 45345/928, originally delivered to Eastern Airlines in January 1958.  Operated by EAL and several flying clubs for less than 10 years before being parked at the St. Paul, MN airport. 
 
The airplane was made ready to ferry during May-August of 2004. With an overnight stop in Atlanta, it arrived in Miami to begin the restoration process. The original interior and hat racks were removed, and placed into long-term storage. They will be available for re-installation come the day the airplane is put on permanent static display. Over 65% of the original aluminum skin, outer wing panels, engines, have been repaired or replaced. A full paint scheme and new interior was completed for the first official Open House in December, of 2008. The airplane has now (March 22, 2010) received the necessary FAA exemption to begin carrying passengers for compensation. This is a wonderful program initiated by the FAA to allow historically significant aircraft to raise funds for its own preservation.
