Special Duties Unit
At Kai Tak Airport, Guan and Todd enter the airport's restricted area as journalists on an airport tour. They slip away from the group, and are stopped by a pair of Airport Security Unit officers. Guan shoots both policemen to Todd's shock. Meanwhile, Soong manages to recover the chemicals. At ATF headquarters, the files found on Todd are cracked, revealing the plans to unleash the chemicals over Cambodia. Ma realises the terrorists may be planning to hijack a plane to seed the clouds, and orders the Special Duties Unit to rush to Kai Tak. He discovers, though that most of them were already erroneously deployed to the new airport site at Chek Lap Kok. Ma orders the remaining 12 officers to the airport hangar.
