Korean Air Flight 85

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.
