Lindsey Vonn's skis didn't release in Olympic crash. Raises years-old safety issues, experts tell AP

Lindsey Vonn’s Olympic crash has renewed pressure to rethink ski bindings, one of the oldest pieces of equipment in the sport. FIS and U.S. Ski and Snowboard leaders say a “smart binding” system is still in early development. Experts say a new algorithm could sense loss of control and trigger a faster release, like the air bag system now required in speed events. Developers warn the timing is tricky, and funding is unclear.
