Tianlong-3, a two-stage kerosene-liquid oxygen rocket comparable to SpaceX's Falcon 9, experienced the failure during a test of its nine engines intended to power the first stage.
At 3:43 pm, the engines were fired according to plan, and the engine thrust reached 820 tons. However, a structural failure caused the rocket to detach from its launch pad and blast off.
All villagers in the area, which is remote and far from the city center, had been evacuated before the test.

probably would be better if they didn't have these flying over populated areas with a bunch of terrifying fuels aboard but what do I know, we have trains carrying the worst stuff ever in our back yards
