Is flying in lightning safe?
有闪电时飞行还安全吗?
Flying in lightning is generally safe because planes are built to withstand lightning strikes. The metal from the plane serves as protection, and aircrafts have lightning protection systems to fight electrical build-up. In fact, the safest place to be in an lightning storm is inside a metal cage such as an aircraft. The FAA even estimates that every plane currently in service in the United States gets hit by lightning at least once a year.
一般来说,在闪电天气飞行是安全的,因为机身能抵抗雷击。飞机的金属外壳起到保护作用,而且飞机装有防雷系统来应对电的累积。事实上,在雷电天气最安全的地方是待在一个金属房里,比如一架飞机里。联邦航空管理局(FAA)甚至估测美国目前在使用中的每架飞机每年至少遭受一次雷击。
Why do your ears pop while flying?
为什么飞行时耳朵会胀胀的?
Ear popping can be an unfortunate side effect of flying, but it isn't one that can be remedied easily. Ears pop because when planes get higher in the sky, the surrounding atmosphere becomes thinner. The air inside the cabin, however, is pressurized to a different level, and according to physics.org, this causes the air trapped in our bodies (and ears) to expand. While there's no way around this happening, experts recommend chewing gum or yawning to sort your ears out.
