The reason why the Canton Tower was demolished by dozens of meters was mainly for safety reasons. Since the Canton Tower is located on the main flight path of the aircraft, excessive height may cause safety hazards to the aircraft. In order to ensure flight safety, the civil aviation department decided to "lower" the Canton Tower after sending a letter and communicating with the Guangzhou Municipal Government. This decision was supported by the Civil Aviation Administration of China and the airport, who conducted multiple calculations and evaluations to ensure that the height of the new TV tower would not affect flight safety. In addition, it is rumored that this decision involves a patented technology from Shanghai, which may be related to the telescopic device of the new TV tower antenna.
