"With hindsight I could have called it a different way, and he could have just come in at the end of the out lap. But frankly I did not expect the penalty that he received."
Whitmarsh revealed that the team only became aware of the fuel situation once Hamilton was on his qualifying lap. "Part way through that last qualifying lap, the data indicated that there was not as much fuel on board as we thought," he said.
