So this gondola in Germany had a full drive train breakdown and folks had to be evacuated. They used a couple interesting ways of getting folks out including, dropping rescuers down to the cabins from a helicopter and the roping the skiers down, also evacing them directly with the helicopter and my favorite is they pulled a firetruck up the hill with a groomer.
