David Pang, speaking at the Airport Council International's annual conference

Airport Authority chief executive David Pang, speaking at the Airport Council International's annual conference, said the crash of an American Airlines aircraft in New York on Monday was a reminder to the industry to show continued vigilance following the September 11 terrorist attacks. 'We just have to do better and better in safety, security and efficiency every day,' Mr Pang told the conference, being held at the Hong Kong Convention and Exhibition Centre this week.
