Four men embarking on a plane ride in Idaho’s ominously named Frank Church — River of No Return Wilderness faced a terrifying moment when the small aircraft hit an air pocket. The plane began to rapidly lose altitude shortly after takeoff and crashed into trees below with head-jolting force.

The men had brought along two cameras to record the highlights of their backcountry adventure. The footage they ended up with was a frightening first-hand account of a plane crash.

The three passengers sustained minor injuries. The pilot, who you can see from the footage took the brunt of the impact, is expected to make a full recovery.

Warning: Slightly graphic images.
