The migration from Kai Tak to Chek Lap Kok is also a story of its own. All the staff and equipment were moved in a few hours from one to another while some of the planes scheduled to land on the new one were already mid-air.
Pilots are awesome. Aviation engineers are awesome. When I observe aviation, I'm always impressed. It really seems like one of the pinnacles of human achievement. Everything from the planes to the pilots to the ATCs and beyond... everyone is just at the top of their game.
