Also, can helos wave at you?

There's one of those white cone-shaped transponder thingys that is a navigation beacon for the old auto-pilot software or so I'm told on federal land that abuts our property.

Anywho, the Coasties are constantly flying around the area and it seems part of their routine is to fly over the beacon is see if anybody's messing with it or whatever. The helos get pretty low sometimes. So we've trained the grandkids to wave at 'em as they fly over. Then one day the helo did a little jig. The rotor stayed level but the craft did a quick rocking motion.

Is that possible?

Nope, completely impossible. Never happened. You didn't see it.

Very cool! I feel confident that the pilot saw and responded. How he did it, I have no idea.
