These are some fun facts about Boeing Commercial jetliners: the 737 is the best-selling commercial jetliner of all time; the Boeing 747 (all versions) have traveled an estimated 35 billion statute miles, that is the equavilent of 75,000 trips to the moon and back. During takeoff, a jumbo jet can devour 2 million liters (528,344 gallons) of air per second. In 1988, commercial aircraft consumed an estimated 70 percent of all jet fuel. Fuel efficiency: 6.7 mpg.
In addition to producing vapor trails that can stretch thousands of miles across the sky, jet exhaust also triggers the formation of artificial clouds by "seeding" the atmosphere with cloud-forming aerosols — droplets of sulfuric acid and particles of soot.
World total revenue traffic — international and domestic in 2014: Passengers 3 303 (millions).
International Civil Aviation Day was established in 1994 as part of ICAO’s 50th anniversary activities. In 1996, pursuant to an ICAO initiative and with the assistance of the Canadian Government, the United Nations General Assembly officially recognized 7 December as International Civil Aviation Day in the UN system (A/RES/51/33).
The purpose of International Civil Aviation Day is to help generate and reinforce worldwide awareness of the importance of international civil aviation to the social and economic development of States, and of the unique role of ICAO in helping States to cooperate and realize a truly global rapid transit network at the service of all mankind.
