Fly up into the sky and float,
Look at the ball of the earth rolling in space,
Seeing the sea from the land,
Looking back at the land from the sea.
Take a look in the air. Understand
——Xu Zhimo's "Wanting to Fly"
People are increasingly choosing
Fast, comfortable, safe, and flexible travel methods
——Flying
But you know
How long does it take to work on an airplane to "retire"?
Number of takeoff and landing times, flight hours, flight years
Three indicators for aircraft "retirement"
One who reaches the standard can retire
Takeoff and landing times: 40000 to 60000 times
Flight duration: 60000-80000 hours
Flight duration: 25-30 years
So where did the "retirement" plane go?
01
Donation to museums, visits, and science popularization
Some aircraft will be operated by airlines
Donate to a museum or exhibition hall
And open to the public
Continue to play the value of visiting and popularizing science
02
Disassembling parts
Some retired aircraft will be dismantled
An airplane can be disassembled into thousands of parts
These parts can be used as second-hand parts
Reused by "Active Employees"
03
Customer to goods
Due to the lower comfort requirements of cargo aircraft than passenger aircraft
Some retired passenger aircraft have undergone strict safety monitoring
Can be changed to cargo aircraft
04
Aircraft Cemetery
For combat aircraft,
Secondary disassembly is not only time-consuming and laborious,
It may also result in the disclosure of confidential technology,
Therefore, some countries have opened special aircraft cemeteries for retired combat aircraft.
Speaking of the plane cemetery,
Most people first think of the Davis Munson Air Force Base in the United States,
There are over 5000 retired warplanes parked there,
Covering an area of up to 2600 acres,
The scale is the largest in the world.
In fact, there are similar "airplane cemeteries" in China.
Pingdingshan Lushan Airport covers an area of about 2800 mu,
More than 2000 warplanes were parked,
The size is second only to Davis Munson Air Force Base.
