Sparks on helicopter rotor blades!

Cool pictures of triboelectrically-produced sparks on helicopters. Start on the 4th picture.

In case those photos don't make it clear, and should the occasion ever arise, never touch a hovering helicopter or anything attached to it like a rescue sling or cargo hook until it has touched ground. The static generated by those blades deserves a healthy dose of respect.

I saw that once in the desert of SW Texas and thought it was pretty awesome. I then went to Panama and as a Blackhawk was coming in at night, I told my buddy to keep an eye on the rotors. The static didn't show up in the damp jungle, unfortunately.

They used that in The Hunt For Red October.
