It’s been one month since tornadoes tore through the small town of Pilger Nebraska. When a Farmers Co-Op recovered its computers from the rubble, no one expected to find anything that worked. However, the security camera hard drives survived, showing an insane view of the storm and the moment it hit.

It’s likely some of the most powerful silent footage you’ll ever see.

Inside the EF-4 tornado that leveled Pilger a month ago. Here’s what victims say it sounded like. We added the audio, so you can hear what they did.

"It wasn’t even real until we were sitting down in that in pretty much the fetal position," Aaron Becker, the President Farmer’s Co-Op Pilger said.

On the other side of eight inch thick concrete walls the farmers co-op security cameras rolled, as 200 mile per hour wind gusts ripped pilger to pieces.

Slow the video down and sparks from snapping electric lines light up the streets, only feet from propane tanks leaking fuel.

Even a lightning bolt caught on camera.

"How quick it moves in and throws that stuff around it. You know it is pretty amazing," Becker said.

This vault saved Aaron, Ryan and four of there co-workers. Because it doesn’t have windows they couldn’t see what was going on outside.

When they escaped, all they could see was rubble. and now because of there security video, they can see how it happened and just how lucky they are to be alive.
