I have NO idea what led to this.  An entire 18 wheeler .... Airborne!

This is dashcam footage taken somewhere in Indiana. While this driver is minding his own business, he sees another driver pull off a stunt that is unbelievable.

No idea whether or not the other driver survived but, I'm leaning toward no on that.  (The crash is at about 3:20.)

(Careful though, the vid is loaded with s-bombs, f-bombs and more. NSFW!!)
