Why can’t Cangkou Airport be moved?
Because Cangkou Airport is a military airport, if you want to relocate, you need to build a new site and complete various handover plans. The city government cannot decide.
The earliest aircraft take-off and landing places were grasslands, usually circular lawns. The aircraft could take off and land at any angle and in the favorable wind direction. There would be a wind direction meter and hangar around it (because at that time Aircrafts are generally made of wood and canvas and cannot be exposed to wind, rain, sun or rain).
After that, the soil field area was started to avoid the added resistance of the lawn. However, the soil field is not suitable for humid climate, otherwise it will be muddy. As the weight of aircraft increases, the requirements for takeoff and landing also increase, and concrete runways begin to appear, which are suitable for any weather and any time.
Another airport known as the oldest in the world is Bisbee-Douglas International Airport in Arizona, USA. This airport houses the first airport in the history of the United States. plane. In 1908 the Douglas Aero Club was formed, and with it the gliders.
