I have tried to look at the bag, as an experiment, several times......it happens so fast and I'm not an owl....e.g. I can't turn my head that far around. Therefore, even though I tried to see it several times, I've never witnessed the bag on deployment.
I've had this discussion with Scott Miller and he recommends not watching your canopy on opening. You will know if you have a mal! Make sure to check for line overs, broken lines, etc.....sometimes you won't feel them right off......but the point is you should look out for other skydivers on opening. Hands on the rears and heads up throughout the opening. Maybe this is a bit off topic but I felt I would post anyway.......
Never Give up! Never Surrender!
