Beth Tweddle produced a breathtaking uneven bars routine and took a huge step towards claiming what would her first Olympic medal, as Great Britain's women gymnasts powered into the team final.
The three-time world champion set the North Greenwich Arena alight with a world class performance, brimming with style and complexity to score a huge 16.133 - putting her in top qualifying place after the third of five sessions.
Britain also secured their place in Tuesday's team final, replicating the efforts of the men's team yesterday, with a score of 170.656.
Tweddle's routine had a 7.0 difficulty score and a huge 9.133 execution score - the largest of the day by some distance.
"I was unbelievably nervous," Tweddle said after qualification. "I've felt sick for the last three weeks.
"My coach said to me: 'Just do what you do in training' and I just thought to myself: 'This is the one moment, and I just have to live for it.'
China's Wu Minxia secured her place in Olympic history with a hat-trick of springboard synchro titles alongside He Zi at today's opening diving event at the Aquatics Centre.
Wu cemented her place as one of the greatest female divers of all time as she also drew level with former synchro partner Guo Jingjing, who she teamed up with to win the past two Olympic crowns, with a record six medals at the Games.
The 26-year-old is set to surpass that mark next week, when she and He go head-to-head in the individual springboard.
This afternoon they were comfortable winners, leading after all five rounds to finish with a gap of 24.30 points from nearest rivals Abigail Johnston and Kelci Bryant from the United States.
Canada's Emilie Heymans and Jennifer Abel took bronze to ensure Heymans became the first diver to win a medal at four consecutive Olympics.
Lizzie Armitstead won silver to claim Great Britain's first medal of London 2012 in the women's road race as Holland's Marianne Vos took gold on The Mall.
Armitstead was beaten to victory at the end of a pulsating 140-kilometre race, which featured two climbs of Surrey's Box Hill.
With the peloton cast adrift, the 23-year-old from Otley near Leeds, was in line for Britain's first medal of the home Games, but the question remained which colour.
Armitstead positioned herself behind the Dutchwoman entering the finishing straight but Vos was strong enough to hold off the Briton, who had to settle for second.
Armitstead said: "I'm really, really happy. Maybe later I'll start thinking about that gold, but I'm happy with silver at the moment.
"I was thinking about trying to play poker in the final and I sat on with about 3k (kilometres) to go and I thought that was my best chance and it came off.
"In retrospect I should've tried to jump Marianne but she's the fastest and I'm happy enough with silver."
On the first British podium place of London 2012, Armitstead said: "It's something very special and it hasn't sunk in yet."
Shooter Kimberly Rhode made Olympic history as the first American to win individual medals at five successive Games - and then insisted there was plenty more to come.

The 33-year-old also equalled the world record with 99 hits out of 100 as she obliterated the field to win the women's skeet.
Rhode was already a two-time gold medallist in the double trap, in 1996 and 2004, won bronze in the same event in 2000 and took silver after switching to the skeet at Beijing four years ago.
But she now has her shotgun sights set firmly on Brazil in 2016 - and beyond.
"I do not see myself quitting any time soon," Rhode said. "I'm looking forward to 2016 and a few more after that. The oldest Olympic medallist was a shooter and he was 72, so I still have a few more in me."
Rhode will have to compete at the 2052 Games if she is to break that particular record, held by Swedish shooter Oscar Swahn who won a silver medal in 1920.
Rebecca Adlington claimed Great Britain's first London 2012 medal in the pool when she produced a performance full of her customary guts, determination and no little skill as she took bronze in the 400 metres freestyle.
The race was won by Frenchwoman Camille Muffat in a new Olympic record of four minutes 01.45 seconds with American Allison Schmitt second.
However, it was a superb performance from defending champion Adlington, forced to swim out of lane eight after only just scraping into the final this morning.
The 23-year-old came from sixth at halfway to touch in 4mins 03.01secs and by the end was closing on Muffat and Schmitt.
Alex Danson was the star of the show with two goals as Great Britain's women's hockey team thrashed Japan.

Cameron van der Burgh and Dana Vollmer broke world records in claiming Olympic swimming titles on Sunday.
