Girl falls into sidewalk sinkhole in China.

A surveillance camera captured an incredible accident: A girl walking down the sidewalk in Northern China while talking on a cell phone was suddenly swallowed up by a hole in the sidewalk 20 feet deep!

Water had eroded the ground underneath the sidewalk, so the concrete had become unsupported.

A crowd gathered to rescue her. A heroic taxi driver jumped in the hole and climbed to the bottom of the pit to rescue her. Firefighters arrived, and lowered a ladder down into the pit and the two climbed out.
