Even ordinary small planes in Alaska are insane, so this cliff-diving experimental cub is about as nuts as it gets.

It's called the Double Ender, possibly because it has twin Rotax engines, and hopefully not because it wants to plummet end-over-end into a glacier from great height. It's gnarlier than the infamous Courchevel, that's for sure.

You can find out more about the craft at its website BushPlaneDesign.com.

Now if you'll please excuse me while I get my stomach out of my throat.
