The National Museum of the U.S. Air Force just discovered that the A-1E Skyraider plane that had been on exhibit since 1968 was still full of 200 gallons of fuel, a major fire hazard. The museum, located in Dayton, Ohio, requires all exhibited aircraft to be defueled, but someone made an error 45 years ago. Part of the museum was closed for a weekend while every aircraft exhibit was inspected. Collectors must be careful. If you find bullets, hand grenades, dynamite, or other war souvenirs stored in a hot attic--or anywhere in your house or on your property--call your local fire department, police department or bomb squad. Explosives deteriorate and can explode if moved carelessly.
