A young boy was watching dad fix his car, when he suddenly had to rescue him from underneath it.
Eight-year-old JT Parker of Sugar City, Idaho, says "angels" helped him save his father's life, after the 1.4-tonne Toyota Prius slipped from the jack, crushing his father Stephen.
JT, weighing only 22kg, adjusted the jack's handle jumping on it, freeing his dad after 15 minutes.
"It was scary, and I didn't think that I could jack the car up, but I just kept on trying," JT told East Idaho News.
Mr Parker is grateful for his son's quick-thinking, but can't remember much of it - he passed out soon after the accident, which broke 13 of his ribs.
Miraculously, Mr Parker suffered no internal damage besides his broken ribs.
JT's mother Jodi said it was a wonder her son managed to save his dad, considering it took the combined strength of Stephen and their 17-year-old son, Mason, to jack it up in the first place.
"There's no way that little boy could have done that. I just felt that it was a responsibility we now have to tell people that miracles still exist," she said.
JT's efforts saw him honoured as one of the Red Cross' East Idaho Real Heroes on Thursday.
