Delivered September 3, 1941, USAAF C-57 41-23166 was sold post war as N60200 to Gannett Co (owner of several US newspapers). The aircraft was converted to a Learstar before delivery to Lockport Felt Co (N711L) in 1957. Coming to Canada for Turnbull Elevator in 1962, it was registered CF-CEC. Flying for several other owners until stored at Montreal in 1971, the C of A expired in 1973. By 1988 the aircraft was donated to the Reynolds-Alberta Museum in Wetaskiwin, AB. Last moved to Trenton, ON for the National Air Force Museum of Canada where parts were used for the restoration of Hudson FK466.

Built in 1953 as N73142 a CV340 for United Airlines, it was converted to a CV580 by Pacific Airmotive at Burbank in 1967 and acquired by Air Ontario in 1984. It was bought by Canair Cargo in 1990 but from there its ownership becomes confused, however what is known is that in November 1992 C-GGWJ, hotly pursued by Canadian Armed Forces CF-18 fighters, landed at Casey Emergency Airstrip north-east of Montreal and was found to be loaded with 4,343 kilos of cocaine flown from Colombia and said to have a street value of C$ 2.7 billion. The aircraft was later flown out and broken up at St. Jean, QC.
