If you're a nervous flyer today, you probably wouldn't have stepped foot on a plane 85 years ago.
如果今天的你一坐飞机就紧张，那么也许你根本不会踏上85年前的飞机。
Back then aircraft would drop hundreds of feet randomly - no wonder there were motion sickness bowls beneath seats - and were almost loud enough on take-off to make passengers permanently deaf.
那个时候，飞机会毫无计划地下坠几百英尺，难怪座位下放着呕吐袋。而且，那个时候的飞机起飞时的声音响得都可以导致乘客永久失聪了。
