Fireball lights up Montana sky after industrial plant explodes: video

Incredible footage captured a massive explosion and fireball at a Montana industrial plant — with the blast rattling homes and cars for miles around, according to reports.

The explosion happened at a saltwater disposal site just outside of Sidney — a small city in northeast Montana — around 8 p.m. Wednesday, lighting up the evening sky with a huge ball of orange flame that billowed into a towering mushroom cloud.

It all apparently started after the facility caught fire sometime Wednesday, with the flames eventually igniting several propane tanks on the property, according to the Sidney Volunteer Fire Department.

Storm chaser Arron Rigsby was driving by when he saw the facility on fire before the explosion, so he pulled over to call for help and dispatched a drone to take a closer look — but got way more than he bargained for.

“All of a sudden, a massive explosion from a propane or oil tank ignited a chain reaction of explosions, sending a shock wave towards town and my vehicle and sent the tank hundreds of feet into the air before crashing back down to earth,” he said in his video.

And the boom was felt as far as 10 miles away, according to officials.

“The fire burned well into the night and with emergency crews on scene, there was nothing to do but to let it burn itself out and keep the spot fires under control,” he explained in his video.

Sidney Volunteer Fire Department soon arrived at the scene and cordoned the area off, establishing a quarantine that was maintained throughout the night.

The department determined the facility was housing multiple propane tanks, and burst when they became heated in the flames.

It remains unclear how the initial fire started.

Remarkably, nobody was hurt in the incident, and the damage was contained to the area around the facility.
