British TV presenter Richard Hammond suffered a memory blank lasting two weeks following his jet car crash in September.
The 36-year-old was filming BBC motoring show Top Gear when the high-speed accident happened.
He told chat show host Jonathan Ross in an interview aired on BBC1: "I was driving and then it was two weeks later and I was in Leeds (hospital).
"Apparently I was awake on the way to the helicopter and I got a bit fighty, I wanted to do a piece to camera, but my eyes were pointing in different directions.
"I have no recollection of that, or the first few weeks. I sort of heard stuff going on but I wasn't in it (coma) for very long. I had post-traumatic amnesia, five-second memory. It happens as a result of brain injury."
