GB Paralympic teen sprinter Jonnie Peacock powered past his hero Oscar Pistorius to grab gold in a hugely tense 100m T44 final.
It was the event everyone was talking about and Peacock delivered - with a new Paralympic record of 10.90 seconds.
The 19-year-old world record holder said: "This is absolutely amazing. I'd like to have run a little bit quicker, but I did enough to hold on."
Defending champ Oscar Pistorius could only finish fourth.
USA's Richard Browne finished second and South Africa's Arnu Fourie third in the Olympic Stadium.
Peacock added: "To hear the crowd chant my name was amazing - that's going to live with me forever."
The 80,000-strong crowd were chanting his name so loudly before the race he had to ask them to quieten down!
Peacock had his right leg amputated below the knee after getting meningitis as a five-year-old.
There were more British golds on the track on Thursday night, with ParalympicsGB now passing its medal target of 103.
Wheelchair racing superstar David Weir made it three golds out of three at London 2012.
The 'Weirwolf' held off tough competition to win the T54 800m.
Weir said: "I had to dig deep tonight - it did hurt." But he added: "I feel like I'm on top of the world at the moment."
He could make it four golds on Sunday when he goes in the marathon.
'Hurricane' Hannah Cockroft lived up to her nickname when she destroyed her rivals in the 200m T34 wheelchair sprint.
She set a new Paralympic record of 31.90 seconds to win her second gold of London 2012, following the 100m.
Cockroft said: "This is what I worked for four years for and I've actually done it now."
In a great night for GB Paralympic athletics, Great Britain also won a silver and three bronzes.
