Some people won't cross paths with a black cat. Others panic when they break a mirror.
And then there are the death-defying passengers who boarded Finnair Flight 666 on Friday the 13th and flew it straight to HEL.
The Nordic airline's notorious Flight 666 took off from Copenhagen, Denmark (CPH), and flew directly to Helsinki, Finland (HEL), today, and we're guessing each and every soul aboard had a devil-may-care attitude about superstitions.
And likely none suffered from triskaidekaphobia, or fear of the number 13.

The 75-minute Flight 666 — which landed safely, by the way — regularly flies to Helsinki, and takes on an even spookier vibe when the trip happens on Friday the 13th, as it has done once or twice a year since the flight began in 2002.
Believe it or not, the creepy details of Friday's flight don't stop there.
According to the folks at @Flightradar24, a Swedish Twitter account that monitors air traffic, the flight took off at 13:00 local time. And the aircraft? It's 13 years old.
Folks on Twitter had some fun wondering just how sinister Flight 666 could get.
Sadly, if you want to experience the thrill of flying Flight 666 to HEL on Friday the 13th yourself, time may be running out.
The famed flight has just one more Friday the 13th journey planned, for October this year.
After that, according to Airlineroute, its flight numbers will be replaced with new digits.
