To the people on Flight SQ321, that would have seemed an eternity. Eight seconds after the captain’s warning, the plane plummeted. Within five seconds, it had dropped a hundred and seventy-eight feet—about the height of a nineteen-story building. There was no time to react, Azmir later told reporters. “Whoever wasn’t buckled down, they were just launched into the air within the cabin,” he said. Azmir had a window seat near the back. When a plane hits turbulence, it tends to seesaw from front to back, so the first and last rows rise and fall the most. “I saw people from across the aisle just going completely horizontal, hitting the ceiling,” Azmir said. “People getting massive gashes in the head.” Some passengers were vaulted up so violently that they dented the luggage bins, or thrust their heads through the panels where the oxygen masks were stored. Those who were standing were sent somersaulting down the aisles; those sitting in the lavatories smashed into the ceiling. It was “sheer terror,” one passenger later said. Then, just as abruptly, the plane lurched up, slamming everyone back to the ground. In just four seconds, the gravitational force on their bodies changed from negative 1.5 g’s to positive 1.5 g’s, Singapore’s Ministry of Transport later noted. It was as if their bodies went from being helium balloons to being sandbags.
但整体上，我没有观察到BD交易热情减弱的趋势。中国医药研发仍具备成本低、效率高的优势，部分跨国药企甚至开始考虑将全球产品的临床前和早期临床试验放在中国。只要这一底层优势不变，BD节奏就不会明显放慢。
