Raymond Benjamin, International Civil Aviation Organization (ICAO) Secretary General, and Tony Tyler, Director of the International Air Transport Association (IATA) told a press conference that both steps are urgently needed to fill gaps in airline safety. Tyler added that the MH17 disaster was strong evidence that modern anti-aircraft weaponry is not under control.
