Aviophobics can breathe a sigh of relief: Thanks to improved technology and stricter regulations, the number of plane accidents resulting in fatalities has fallen dramatically over the years. But this doesn't mean it's all smooth sailing: In fact, in 2018, the year after this chart was released, plane crash fatalities rose sharply.
As for plane hijackings, they're practically nonexistent at this point. Wondering why this graph shows such a huge spike in "skyjackings," as they were called, between the '60s and '70s? During those years, a rash of hijackers took advantage of lax regulations to, among other things, demand ransom on the regular. There were even instances of multiple hijackings happening in the same day!
Happily, those days are over and flying is now (mostly) a perfectly safe pursuit.
