LATEST: British TV presenter RICHARD HAMMOND has shown signs of improvement in hospital after crashing a jet car at nearly 300 miles (483 kilometres) per hour yesterday (20SEP06). The 36-year-old was attempting to break the British landspeed record for BBC car show TOP GEAR when the accident happened at a former Royal Air Force airfield near York, England. Sources at Leeds General Infirmary say Hammond is improving but is still seriously ill. He has been joined at his bedside by Top Gear co-presenters JEREMY CLARKSON and JAMES MAY. Clarkson said in a statement that Hammond and his family are "the most important concerns we have. "I would just like to say how heartened Richard will be when I tell him just how many motorists and truck drivers on my way here wound down their windows to say they were rooting for him."
