"Get the team together. Raiden is drunk again."

A high-speed camera captures a rare upward lightning in Rapid City, South Dakota.

But all land-air lightning travels upward, no?

It's explained in a link from the yt vid, which I overlooked when posting (sorry!):

In 99% of cases the current flows the other way, from the clouds to the ground. This vid is related to a study by atmospheric scientist Tom Warner of the South Dakota School of Mines and Technology in Rapid City. He says companies running wind turbines are particularly interested in why 1% of lightning strikes go upwards, wanting to know what conditions favour it and how the effects can be mitigated. There is a link to the paper in the blog article linked above.

Adding video to channels (Timeshift) - requested by ant.

What's rare is how slowly it moves.

Really, though; this is spectacular! I love how the little sparkies lead the raching plasma streamers. Looks like cheesy special effects, but better.

There can be only one explanation.
