Five U.S. Army Airforce Fairchild C-82 Packets were lined up at Blue Grass Field in August 1948. Designed as a heavy-lift cargo aircraft, they flew in from Greenville, S.C., to pick up freight consigned by the Lexington Signal Depot to Eglin Field in Florida. These aircraft also were used in the Berlin Airlift, primarily to bring large disassembled vehicles into the city. This weekend, the Aviation Museum of Kentucky is hosting a C-54E Skymaster named The Spirit of Freedom, which also was used in the 1948-49 Berlin Airlift. Visitors can tour the aircraft 10 a.m. to 5 p.m. Friday and Saturday, and 1 to 5 p.m. Sunday. Herald-Leader Archive Photo
