Bumper-to-bumper on the the hurricane highway. What may have been the most impressive and packed day of the olympic games. Bill weir has had a front-row seat the whole way. He joins us now. Take it away, bill. Thanks, george. Gorgeous day 15 here in london. We had to get out of the studio and come down to the thames, that here in the land of the queen, women killing it for usa. Women winning more golds than the men. And team usa got vengeance for that world cup loss of a year ago. It was 389 days ago, when this japanese team beat these american women. And team usa's bit-chomping days of redemption took just eight minutes. Alex morgan, boots the ball across. Carli lloyd, waiting with the header. 1-0, usa. But japan stayed aggressive. Goalie hope solo had to keep defense tight. In the 54th minute, thanks to carli lloyd once again, drilling the goal from 20 yards out. That's a goal by carli lloyd. Reporter: Japan fought back with a gritty goal two minutes later. 2-1 game. But as the time wound down, the massive crowd at wembley knew this night was turning red, white and blue. It's all over. Redemption for the united states. Reporter: The women take america's fourth gold in five olympics. Usain bolt going for the unprecedented double-double. Hoping to win both sprints in back-to-back games and cement the legacy of fastest man alive. Fastest man ever. Usain bolt -- Reporter: And to make it sweeter, he leads a jamaican sweep.

All the news after two days of running, jumping and throwing, americans ashton eaton becomes the decathlon champion. Greatest athlete in the world. Trey hardee takes silver. Look at the effort on their face. Good job. Claressa shields, grew up with a dad in prison, a life of abuse. Now, the 17-year-old, first american woman ever to win olympic boxing gold. Great story. Not to be undone by their teammates on the soccer pitch, the women of water polo got gold. How do you celebrate? Everybody in the pool, of course. And 129 medical ceremonies found that 40% of people sing their anthem. And 16% cry. Women, a lot more than men. But when men cry, they really lose it. When it comes to nations, china cries the least. Great britain, the most. I have to admit, I got a little misty a couple times during "god save the queen."
