Belgian bobsledders An Vannieuwehnhuyse and Sophie Vercruyssen spent nearly 30 seconds sliding upside down, making the final eight turns on the track, after crashing in a World Cup race in Whistler, B.C., on Friday night.
They finally slowed to a stop after crossing the finish line nine seconds behind the fastest sleds in the first of two runs.
The athletes quickly emerged from the sled, but they did not qualify for a second run later that night.
The Whistler track has been known for its difficulty since it opened one year before hosting the 2010 Olympics.
