omer mei-dan, now that name is a blast from the past. BD 2008 he was there conducting a study on BASE jumpers. cool cat. did the surveys we filled out ever result in a published article? i've often wondered...
Sounded to me like he said 3000 base jumpers of that 10% use wingsuits. So of that 300 6-7% die a year. 6 percent of 300 is 18 which seems like decent estimate.
