"Oh Shit" moments...

Looking back at my chainslip moment when accelerating from a trackstand, I have come to the conclusion it wasn't a chainslip (as my tension is fine), but it was actually wheelspin which made me poo my shorts. Is this possible? Has it actually happened to anybody?

Do you have any skid patches? Happened to me yesterday. Took me and the angry ass driver behind me by complete surprise! No wet, tensioned and lockring toight as a toight toiger. It was the missing rubber that caused the slippage. Accelerating on the bit without any traction.
