Two Pilots traded punches with other crew members in mid flight in front of passengers. An Air Hostess on an Air India flight accused the men of sexual harasment. The Airbus A-320 was on a flight from Sarajar to Delhi .

An article from the Times says that "the cockpit of the A320 was reportedly left unmanned". Obviously that's less than definitive but still quite disturbing.

 Yes, you are quite right the cockpit was left unmanned. There is a ruling that the control of the aircraft must be monitored by a qualified person at all times. I think it is more of a serious matter than the fighting.
