Alex Stack was driving on I-96 when she used her Vine app to film a truck driving next to her go airborne, and fly off of the road.

She said that she looked over and noticed a truck driving in the median of the expressway.  That's when she pulled out her cell phone and started filming.

The video she recorded and posted to Twitter is amazing!  Luckily the driver of the truck is expected to make a full recovery after this insane accident.
