Sprinter Richard Whitehead has powered to gold on the track, breaking his own world record to take victory in the 200-metres T42 final as ParalympicsGB moved to second in the medal table.
The 36-year-old double amputee stormed home with enough time for a "two-gun salute" bicep flex as he crossed the line.
Whitehead, from Nottingham, said of his world-beating victory: "It's all about guts and determination. Today I came, I saw, I conquered.
"That was what the two-gun salute was all about - in honour of my hero Chris Hoy."
Just minutes after Whitehead's win, Natasha Baker won ParalympicsGB's first equestrian gold medal at Greenwich Park.

His victory came after his disqualification in the C4/5 1km time trial event after an alleged starting gate malfunction.
Meanwhile, at the Olympics Stadium, Gemma Prescott, 28, won bronze in the F32 club throw, with Rob Womack, 41, matching the feat in the shot put.
