Airport flight display returns to normal after glitch

The Airport Authority (AA) said real-time updates on its terminal display screens were gradually resuming on Sunday afternoon, hours after a glitch in its flight information display system. The AA said no flights were cancelled but a few were delayed due to the system failure. Ricky Leung, the authority's executive director of engineering and technology, said there was no evidence it was a hacking attack, and that they will later examine the system in detail. "We will actually do more thorough checking in the rest of the time... There is no hacking activity we've identified so far. In terms of maintenance, it's mainly maintained and operated by our own in-house personnel," he said. The AA has said all airport operations were normal as it was trying to fix the glitch. Secretary for Transport and Logistics Lam Sai-hung said he's very concerned about the incident, and told the authority to investigate the case and submit a report to the government.
