Investigators are still putting together the pieces, but from what we know so far, it¡¯s likely that 27-year-old German co-pilot Andreas Lubitz committed mass murder-suicide when he flew a Germanwings passenger jet carrying 149 passengers and fellow crewmen into the French Alps.

Authorities say they haven¡¯t found a suicide note, but it¡¯s a safe bet that Lubitz¡¯s final act was prompted by depression (they found the meds), diminished vision, a deteriorating romantic relationship and his worry that the Lufthansa subsidiary would ground him if they found out about his problems, crashing a career he loved and blowing up his livelihood.

Though rare, pilot suicide isn¡¯t unheard of. As long as the current system remains in place, it will happen again.
