A speeding car launched into the air and landed upside down on the roof of a house.
Police say the early morning crash in Houston, Texas, happened when the driver was speeding and failed to take a bend in the road.
The crash triggered Susan Mistini's house alarm system and she thought someone was breaking into her home until a neighbour told her what happened.
Ms Mistini said: "He said, 'hurry up there's a car on your roof'. A car on my roof? And he said, 'yes a car on your roof'."
Harris County Sheriff's Assistant Chief John Laine said: "(The car) inverted and somersaulted and landed on the roof upside down."
The driver was taken to hospital and is in stable condition.
Investigators have not determined whether or not alcohol was a factor in the accident.
