Wickers, our household has had a decent pair of skis written off by baggage handlers. As we did not see it happen, and did not open the ski bag and make a visual inspection before leaving the airport, we were left with a pair of written off Blizzard Thermo's (it was a long time ago)
Big Clue.......
Dusty vehicle tyre tracks imprinted on the ski bag
At the time, like most travellers, we were just happy to see the skis eventually appear in the baggage hall. How many folks would then unwrap their kit and examine it closely?
