As the rain from Hurricane Helene came down harder and harder, workers inside a plastics factory in rural Tennessee kept working. It wasn’t until water flooded into the parking lot and the power went out that the plant shut down and sent workers home. Several never made it.

The raging floodwaters swept 11 people away, and only five were rescued. Two of them are confirmed dead and part of the death toll across the affected states that passed 150 Tuesday. Four others are still unaccounted for since they were washed away Friday in the small town of Erwin, Tennessee, where dozens of people were rescued off the roof of a hospital.

Some workers managed to drive away from the plant, while others got caught on a clogged road where water rose enough to sweep vehicles away. Videos show the brown floodwaters from the adjacent Nolichucky River covering the nearby highway and lapping at the doors of Impact Plastics. Jacob Ingram, a mold changer at the plastics factory, filmed himself and four others waiting for rescue as bobbing vehicles floated by.

He later posted the videos on Facebook with the caption, “Just wanna say im lucky to be alive.” Videos of the helicopter rescue were posted on social media later on Saturday. In one video, Ingram can be seen looking down at the camera, a green Tennessee National Guard helicopter hovering above him, hoisting one of the other survivors.

In another, a soldier can be seen rigging the next evacuee in a harness. Impact Plastics said in a state.
