1979: THREE-MILE ISLAND DISASTER. Thru 15 Apr MAC flies 15 support missions. The aircraft deliver a 40,000-pound rawindsonde station (a radiosonde is tracked by a radio direction-finding device to determine the velocity of winds aloft), lead bricks and shielding, a water filtration unit, charcoal filters, and potassium iodine for the cleanup. Later, the aircraft fly out barrels of contaminated water. #airlift #Rescue
