PPG recently supplied coatings and sealants to help restore a 74-year-old, four-engine transport aircraft – the Douglas C-54 Skymaster, serial number 56498.
Manufactured in 1945, the aircraft was used by the U.S. Army Air Force as a workhorse to transport medical supplies, troops and military equipment during World War II, the Korean War and the Vietnam War. It left military service in 1973 and was flown as a sprayer from 1975 to 1985.
