In July 1967, Forrestal departed Norfolk for duty in waters off Vietnam. In the Gulf of Tonkin on 29 July, Forrestal had been launching aircraft from her flight deck. For four days, the planes of Attack Carrier Air Wing 17 flew about 150 missions against targets in North Vietnam from the ship. On 29 July 1967, during preparation for another strike, a Zuni rocket installed on an F-4 Phantom (#110), misfired, impacting an armed A-4 Skyhawk, side #405, parked on the port side (U.S. Navy Judge Advocate General Investigation Report of USS FORRESTAL Incident). The rocket's impact dislodged and ruptured the Skyhawk's 400-gallon external fuel tank. Fuel from the leaking tank caught fire, creating a serious conflagration that burned for hours, killing 134, injuring 161, destroying 21 aircraft and costing the Navy US$72 million. On the flight deck that day was Lieutenant Commander (later Senator) John McCain.[7]
