Oscar Pistorius returned to London and to Paralympic competition with a new world record.
The South African, who last month became the first amputee sprinter to compete in an Olympics, clocked 21.30 seconds to win his heat of the T44 200m with effortless ease.
His crossover into able-bodied competition has made the Blade Runner a Paralympic icon and he received a huge ovation from the capacity crowd at the Olympic Stadium.
"I just wanted to come out tonight and have a good race," he told Channel 4.
"It makes me so happy to be here. I'm happy with the time.
"Tomorrow's the big race (the final) and I am looking forward to it. To run in front of such an amazing stadium is mind-blowing."
