Whats going on at BMED. Another flight cancelled from CIS due F/O and Capt having huge punch-up in a bar. Cabin crew refuse to operate home and flight schedule 'up in the air'. This is not the first time this has happened at Bmed. Exactly same thing happened in CIS few years back when skipper and f/0 had scrap - flight not cancelled and also a few years back a crew refused to fly home with a capt from amman as they were concerned about his ability to fly the aircraft home.
