There was a hijacker. He had committed many international crimes. The police or the FBI never caught him. Then he was going to hijack a private jet. He planned to dress up as a man with a coat and a hat to not look suspicious. He drove to the runway and parked his car. He then pursued a jet cleaner. Without letting the officers see him, he sneaked up to the jet cleaner and killed him by twisting his neck. He wore the jet cleaner's uniform to disguise himself. He was acting as if he was cleaning the jet, and he snuck up behind the air hostess and killed her. He got into the plane without being detected. He snuck in and went throughout the plane to see if any staff were there; fortunately for him, there weren't any.
