Several things happen at or around this time. Flight 11 veers off course, now heading towards Albany, New York. It also stops transmitting its IFF (Identify Friend or Foe) beacon signal. Flight control decides at this time that the plane has likely been hijacked.
In addition, American Airlines Flight 77 takes off at this time from Washington Dulles International Airport. Like American Flight 11 and United Flight 175, it is bound for Los Angeles, and like the other two, will never arrive.
At around this time, Daniel Lewin (above), a passenger aboard Flight 11, and former Israeli Special-Ops member is killed, becoming the first 9/11 fatality.
