On September 11, 2001, Korean Air Flight 85 was en route to Ted Stevens International Airport in Anchorage, Alaska. When information about the September 11 attacks went out, the pilot communicated with the airline via text message, including the letters "HJK". This was thought to be a covert signal that the flight had been hijacked and, when ordered to squawk 7500 (a "hijack" code), the pilot complied instead of saying he would disregard the instruction.〔(【引用サイトリンク】title=Second Controller Speaks About Korean Airliner Incident on 9/11 )〕 Flight 85 was ordered to divert to Whitehorse, Yukon, Canada. American officials and the Canadian Prime Minister Jean Chrétien authorized the aircraft to be shot down if it did not cooperate. The airliner pilots complied and the 747 landed safely in Whitehorse, with American F-15 military jets escorting it. ==Incident== After the September 11 attacks, a call went out for all planes to return to their airports of origin (or if they did not have enough fuel, to land in Canadian territory). While discussing the day's events with the Korean Air office, the pilot of Flight 85 included the letters "HJK" (the code for "hijacked") in an airline text message.〔 When the pilot sent his message, the text messaging service company, Aeronautical Radio, Incorporated (ARINC) noticed the "HJK" code.〔 ARINC officials, worried that the South Korean pilots might be sending a coded message for help, notified North American Aerospace Defense Command (NORAD). Taking no chances, NORAD scrambled F-15 jets from Elmendorf Air Force Base in Anchorage to intercept the 747, with Alaska air traffic control (ATC) asking the pilots coded questions. Civil airline pilots are trained to answer these questions in a coded way if hijacked. ATC instructed the flight to change its transponder code to 7500, the universal signal for hijack, expecting that, if they had not been hijacked, the pilots would respond to that effect. Instead, they simply complied with the instruction, which ATC took as confirmation that the flight had indeed been hijacked.〔 Worried that a possible hijacked plane might strike a target in Alaska, Governor Tony Knowles ordered the evacuation of large hotels and government buildings in Anchorage. At nearby Valdez, (also in Alaska), the U.S. Coast Guard ordered all tankers filling up with oil to head out to sea. Lt. Gen. Norton Schwartz, who was in charge of the NORAD planes that scrambled to shadow Flight 85, told reporters in 2001 that he was prepared to order the South Korean airplane to be shot down before it could attack a target in Alaska.〔 With NORAD telling Anchorage ATC that it would shoot down the airliner if it came near any potential targets, these controllers informed Flight 85 to avoid all population centers and head out of the country to Whitehorse, Yukon. NORAD promptly called Canadian authorities seeking the go-ahead to shoot the plane down over Canada: Ninety minutes after the South Korean pilots changed their transponder signal to the 7500 hijacked code, the plane landed safely in Whitehorse. Canadian officials evacuated all schools and large buildings before the plane landed.〔 On the tarmac, Flight 85 was greeted by armed Royal Canadian Mounted Police officers who, after interrogating the pilots, learned the whole ordeal was caused by a translation error. The South Korean pilot stated that he had been ordered by Air Traffic Control to change the transponder signal and Air Traffic Control confirmed having done so.〔 Korean Air still uses Flight 85 on its Seoul-Incheon to New York-JFK route. However, the flight no longer stops in Anchorage and its normal equipment is now the Airbus A380. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Korean Air Flight 85」の詳細全文を読む スポンサード リンク
