According to CoinMeta, a flight safety incident occurred with the helicopter carrying U.S. President Donald Trump in Washington at the beginning of August, which attracted widespread attention. The National Transportation Safety Board of the United States stated in its preliminary investigation report released on August 27 that at the time, Trump's "Marine One" helicopter was too close to a commercial airliner due to communication issues between the helicopter crew and air traffic controllers, and recent construction activities at the White House also played a certain role in this incident.
