I just did some calculations, and if I got them right, if you tossed a stone into that shaft it would take 14.5 seconds to hit the bottom. There would be another three seconds before the sound reached you back at the top.
When it hit it would have been doing 510 kph (317mph) less wind resistance.

I got slightly different numbers, but I didn't account for bouncing off the walls on the way down.
