On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in.
Airplanes are disassembled at aircraft-recycling centers where non-metal components with no recycle value are discarded, major components are dismantled and metal alloy components are sorted based on their composition. The metal alloys are then remelted together to form a single homogenous alloy from scraps.
While the average age of a U.S. domestic commercial airliner is 11 years old, it is not uncommon for aircraft to still be in service at 24, 25, even 30 years old.
Chou did the math, and it turns out that frequent fliers actually age the tiniest bit more quickly than those of us with both feet on the ground. Planes travel at high enough altitudes that the weak gravitational field speeds up the tick rate of a clock on board more than the high speeds slow it down.
Flying Is Only Getting Safer Over TimeGlobal flight accident rates have been steadily declining over the years for a number of reasons, according to the International Civil Aviation Organization (ICAO).
According to Drela, today's airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)
The prototype was rolled out in April 1994, and first flew in June. The 777 entered service with the launch operator United Airlines in June 1995. Longer-range variants were launched in 2000, and first delivered in 2004.
Child age at the time of unaccompanied travelChildren ages 15-17 are permitted to travel as a standard passenger, Go to footer note, provided they can present a valid ID to security personnel. If parents or guardians prefer, they can also travel as an unaccompanied minor.
Sure, the 747 is a Type Certified and airworthy aircraft, the FAA does not really care who owns it so long as they play by the rules. Boeing even sells them directly to the private market via their BBJ line. There are even a few used ones listed for sale right now.
