A US police officer has watched on helplessly as a massive gas explosion lit up the night sky after a pipeline ruptured alongside a Texas highway.
The officer attached to the Spearman Police Department put his foot down and sped towards the massive mushroom cloud blast that rocked Hansford County last night.
The incident was caught on his vehicle's dash cam.
Officials from DCP Midstream who manage the natural gas pipeline told local media the blaze is under control and will eventually burn itself out once emergency crews finish repair work.
Nobody was injured in the explosion.
