A 32-year-old man was pronounced dead after becoming unruly on a Red Wings flight from Moscow to Simferopol. The man became unruly shortly after take-off claiming that the pilot was asleep and that everyone was going to die. He then tried to strangle a woman, which led to a brawl as others intervened. The crew restrained but he then fell unconscious; the flight returned to Moscow. Medical staff tried to resuscitate the man on landing but he was pronounced dead due to heart failure.
