1 - It's flight number 666.
2 - Today is Friday the 13th.
3 - The airport it's flying into is abbreviated HEL.
From the full article:
Finnair has been making the flight for many years, but it gets particularly attractive whenever it happens on Friday the 13th.
This writer's definition of "attractive" apparently differs from mine. Attractive maybe, if you're a masochist.
"It has been quite a joke among the pilots. I'm not a superstitious man. It's only a coincidence for me," pilot Juha-Pekka Keidasto said previously.
Hilarious, those Finnair pilots. Oh, and just so you know:
Flight AY666 from Copenhagen to Helsinki took off at 12:15pm GMT and landed safely at 13:31.
Finnair 666 cheats the fates again and lives to fly another day.
