从撞击开始计算，30秒后飞机降落跑道，同时机组人员抚慰乘客情绪，确认可以避难的通道和舱门；3分48秒后机舱内出现烟雾；6分20秒后打开舱门，避难开始；7分30秒后绝大部分乘客完成逃生。
此后机长继续留在机舱内，一排一排座位确认有没有无法独立逃生的乘客，并成功发现解救几位；撞击发生后的18分钟，机长在确认完所有人员顺利避难后，自己完成逃生。两分钟后，飞机舱内燃起熊熊大火。 source

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
