Chaos in Wilmington, NC — a car plowed into a building’s gas line, sparking a massive explosion that injured three firefighters… and the whole thing was caught on camera.

Check out these videos taken from onlookers Tuesday … smoke billowed from Eastern Carolina Veterinary Medical Center as debris rained from the sky — all after a car lost control on a turn and crashed into the building.

It’s still unclear whether the collision sparked the explosion outright — or if the gas line blew moments later.

According to WECT-TV, firefighters rushed in — at least four were injured, with one sustaining severe burns.
