Im fairly sure I have more skydives than you so, Im not sure where you got THAT statistic. Nor how you would compare the two. Miles per incident? Time between incident?
Skydiving itself is statistically pretty safe. 15 - 20 fatalities per millions of jumps per year worldwide. And most of those fatalities are caused by pilot error. Very few actual parachute malfunction induced fatalities. However when you get into individual disciplines within skydiving (freeflying, wingsuiting, CReW) the fatalities per jump goes up. When you get into the less safe disciplines (BASE, proximity flying) the fatalities per jumps increases even more due to less participants vs more fatalities. You cant really compare airline stats to extreme sport stats.
That said, how did those guys not snag their BALLS on some of those buildings!!??
