I once buried a saw in my calf at around 175-180 ft, and as you said, it happened in the blink of an eye. Gawd that fucking hurt. I calmly let the guys on the ground know that I had just done something stupid, and asked them if they could kindly fire up the trunk cause I was coming down. Man that was a long decent to the ground!Super wierd feeling. So fast. I felt the chain instantly. Ripping.....and knew I fucked up.....
I would note that Paul's story is a good reminder as to why we should always have quick egress to the ground gentlemen.
