I don't know if it was acurate, but the reconstruction I saw on television showed the Pilot holding short of the runway and querying with ATC whether he should proceed more than once.
He even told the Contoller which holding point he was at, and was still told to proceed.
As I said, I don't know if the reconstruction was completely acurate, but it seemed well researched.
As with everything in life, it is rarely one event that causes a tragedy, more usually it is a chain of events.
