Rio opens Games for 'superhumans'

Rio de Janeiro opened the Paralympic Games with samba, parading wheelchairs, giant balloons -- and loud booing of Brazil's president -- at a sold-out Maracana stadium. The extraordinary sight of US Paralympian Aaron Wheelz jumping in his wheelchair from a 55 feet (17 meters) ramp got the crowd on its feet. Then the joyous rhythms of samba singers and a carnivalesque reproduction of a Rio beach scene got them dancing.
