Response to social media discussions about and media enquiries of aircraft noise (revised)

In response to the discussions on social media held by the Macao residents since yesterday night and the media enquiries about the aircraft noise, the Civil Aviation Authority provides information as follows: 

In accordance with the time of which the discussions were held by the Macao residents on social media, the Civil Aviation Authority has then acquired the flight information from the Macau International Airport. The flight was the cargo charter service operated by GEL Airline Geo Sky LLC (registered in Georgia), departing from Macao for Islamabad with flight number GEL921. The aircraft type was Boeing 747-200. The flight departed from the Macau International Airport at 20:23. After flying from the Macau air traffic zone into the Zhuhai airspace, due to the air traffic situation in the neighbouring area, the flight was instructed by the air traffic control to turn left at a time earlier than the original time on the designated flight route and therefore passed through the Macao peninsula at altitude above 4,500 feet.
