Delivered to TWA as N40439 in 1952. Sold as N67B in 1959 then N671L in 1961. To Piedmont Airlines as N40403 in 1965. Sold in 1968 and stored at Sebring, FL. To PBA-Provincetown-Boston Airline in 1977 and used for parts at Naples, FL. Scrapped in 1994.

Operationally this 727 was with Northwest Airlines (1965-78), Piedmont Airlines (1978-1982), United Technologies (1982-1984 as a flight test bed) and Key Airlines from 1984. Retired by Worldcorp Leasing in 1993, the airplane was stored at Mississippi and broken up by 1996. Historically significant as the 727 associated with the passenger known as D. B. Cooper and his 1971 $200,000 extortion of Northwest Airlines. After getting the ransom, Cooper escaped by jumping out of the airplane while in flight via the rear airstairs with the money and a parachute..... never to be heard from again.

Ex Northwest N467US. Operated by Piedmont from June 1978 until January 1984.

Still showing the very faded colours of its former owner Piedmont Airlines, and even its name "Mount Mitchell Pacemaker" can still be seen below the cockpit windows, also very faded. Piedmont used this old TWA aircraft (ex N40439) between 1965 and 1968. It passed through the hands of some brokers before ending up as a spares ship with PBA at Naples, FL in 1977. It was completely scrapped during the early 1990s.
