Multiple Tailgates and Cravats
Lineover is not the only mal possible with unpacked jumps. A guy from the Moscow crew 2 years ago did a rollover from a 116-meter {B}. He got a 180, hit the wall and scratched it all the way down to the ground. (Miraculously got away alive with no broken bones, only heavy bruises and cerebral concussion. Jumps in good health now). Experienced people said that not priming the tailgate may have been a contributing factor to the offheading - at linestretch the tail caught air first and the canopy started to inflate asymmetrically. I have nothing else to add as I have no unpacked experience and am not going to have one soon. But it would be interesting for me to read educated opinion on this.
Thanks.
Edited to add: Of course, I know that making a rollover from B. is a bad idea. My point is not about that.
