"The U.S. Marine pilot safely ejected from the single-seat aircraft and is currently being evaluated by medical personnel," said a statement from the Marines. "There were no civilian injuries." The cause of the crash is under investigation. The F-35 is the world's most expensive weapons project and has been bogged down in delays and unexpected costs for years. Each plane costs about $100 million, depending on its features. This is the first time an F-35 has crashed.
