I witnessed three deaths on ski slopes: one in Austria, one in Switzerland, and one in France. No one wore a helmet in those days, but running into a tree or a lift pylon at speed could easily result in death. running into another skier usually did not produce a death.
I doubt the a helmet would have made a difference in the three accidents that I witnessed, but a collision between two skiers, a helmet may have saved a life. I skied with members of the U.S. Ski team, in a training mode for instructor certification. Their skills were so much beyond mine that it defies description. Most amateur skiers frequently ski beyond their skill level. I certainly did so.
Why doesn’t Brandon mandate wearable airbags for all skiers? If we only save one life.....
The videographer guy at Mt Hood Meadows in the early 80’s was one legged. You paid the fee, and he would follow you down any slope,run, or trail with the camcorder on his shoulder.
He was quite impressive.
