full_context: Document 1: Eastern Air Lines Shuttle Flight 1320: Eastern Air Lines Shuttle Flight 1320, carrying passengers from Newark to Boston was hijacked around 7:30 P.M. on March 17, 1970 by John J. Divivo who was armed with a .38 caliber revolver. Captain Robert Wilbur Jr., 35, a former Air Force pilot who had only been promoted to captain six months prior, was shot in his arm by the suicidal hijacker. Despite his wounds, he flew his aircraft safely to a landing while talking to the tower, telling them his copilot was shot (but not himself) and needed an ambulance. His copilot, First Officer James Hartley, 30, was shot without warning by Divivo and collapsed. Despite being mortally wounded Hartley recovered sufficiently to rip the gun from Divivo's hand, and shoot the would-be hijacker three times before lapsing into unconsciousness, and eventually death. Although wounded and slumped between the seats, Divivo arose and began clawing at Captain Wilbur, attempting to force a crash. Wilbur hit Divivo over the head with the gun he had retrieved from the center console. The pilot was able to land the plane safely at Logan International Airport, and the hijacker was arrested immediately. On November 1, 1970, DiVivo hanged himself while awaiting trial at Charles Street Jail.
