I am certain they have thought of a thousand, a million things that would never even have crossed my mind. But if you look back at the 20-something pages we have, the one thing that I keep stressing is their delayed response in deploying helicopters. Could this not have been one thing that they overlooked? 你知道百密一疏是甚麼? If they didn't think it was effective, why was this line of rescue operations added on day 3 / 4?
