Gorgeous wing-tip vortices from an airliner landing in fog

This short video is a sleeper...

It's only 50 seconds long and you start wondering whether it was worth the click through.

Then...wow.


I am so going to have to take the camera out to the Canberra Airport next foggy morning...

It's a Swiss Air A340 landing in Zurich, and was published in January this year by Andy Ruesch. And it's a pretty good example why formation flying is kind of dangerous.
