"Oh Shit" moments...

I just had my chain come off while pedalling like a loon down a steep hill. Chain jammed chainring, locked the rear wheel, and I skidded for a while until the rear tyre exploded.
I managed to keep it upright, steering into the fish tailing skids as if I knew what I was doing but sadly had to call the wife taxi as the hole in the tyre was way too big for a repair.

Nice work, well handled. Glad that a new tire is the extent of the damage.
