On the alien UFO cause, since in the USA all non-citizens are officially
"aliens" and non-citizens do paddle there, there must be some non-negative
probability of a kayker in the USA being killed by one. How much white
does there have to be in white water before a kayak is considered
airborne?

And considering the shape of some whitewater boats I've seen they could
definitely qualify as unidentifiable.
