A BBC report into the Top Gear crash that nearly killed host Richard Hammond last September has blamed tyre damage.
The report attributes the accident to the "catastrophic disintegration" of the jet car's front tyre, probably caused by an object such as a nail.
But the 88-page document criticises the Top Gear team for not having anyone present "with sufficient knowledge to assess the adequacy" of safety checks.
Hammond crashed while driving at speeds up to 288mph at an airfield near York.
