The day has been celebrated by the International Civil Aviation Organization since 7 December 1994, the 50th anniversary of the signing the Convention on International Civil Aviation. The day is still celebrated around the world for the people of the aviation community like ATC (air traffic control), airport management, airlines and of course the aircraft themselves. This day also celebrates almost disaster flights like QF32 (which no one died or was injured) and others that were in disaster but the pilots and crew managed to save the passengers and most of the plane. But then also the terror of the event 911 and the worlds worst plane to plane collision between a KLM 747 and a PAN AM 747 at Los Rodeos Airport (now Tenerife North Airport), on the Spanish island of Tenerife, Canary Islands. We need to celebrate for CASA, FAA, NTSB, ASTB and other aviation safety and investigators around the world so that today's aviation stays much safer than it was.
