Beijing Daxing International Airport has the largest aircraft hangar in Asia. The hangar covers nearly 40,000 square meters, equivalent to five football fields or 96 basketball courts. The hangar has space for three wide-body airplanes and three narrow-body ones. It can facilitate simultaneous base maintenance on 12 airplanes, including two A380 and three B777 wide-body aircraft. CGTN reporter You Yang makes an exclusive visit to Asia's largest aircraft hangar and gets a closer look at an A330 that is being maintained.
