About 20 students from STAF Tam Pak Yu College had the rare chance to watch on-the-spot the commercial flights touching down the runway of Hong Kong International Airport (HKIA) and caught a glimpse of the airfield during their visit to CASL on 15 April 2016. Besides exploring the duties of aviation unsung heroes - engineering professionals, ground support and cabin services teams, they gained better understanding of the operation of HKIA and the dynamic aviation industry.
