Fourth of July
Three young men in Oklahoma were enjoying the upcoming Fourth of July holiday and wanted to apparently test fire some fireworks.
Their only real problem was that their launch pad and seating arrangements were atop a several hundred thousand gallon fuel distillation storage tank. Oddly enough, some fumes were ignited, producing a fireball seen for miles.
They were launched several hundred feet into the air and were found dead 250 yards from their respective seats.
