HALEIWA, Hawaii (AP) -- A retiree who lives across the street from a Hawaii beach said she heard two booms that were loud enough to shake her house on the night two Marine Corps helicopters crashed off the island of Oahu. "I threw my blanket off, put my slippers on and ran outside thinking it was a car accident," Elaray Navarro said. The Coast Guard was notified late Thursday of the crash by another civilian who saw the aircraft flying then disappear and a fireball. Someone else reported a flare in the sky, Coast Guard spokesman Lt. Scott Carr said.
