Today’s Topic — Parachuting — how dangerous? what’s the best metric? what is your risk threshold?
Where do you draw the line on risk when it comes to sports? Today, I decided to check out the riskiness of parachuting. How many fatalities per year? How does the death rate compare to say driving a car? What are the typical safety precautions? Experts — please chime in. Correct, elaborate, elucidate.
US FATALITIES PER YEAR — PARACHUTING
1. 1970s: 42.5
2. 1980s: 34.1
3. 1990s: 32.3
4. 2000–2009: 25.8
5. 2010: 21
NB: Injuries requiring “resort to a medical facility” in 2017: 2585
COMPARISON — RELATIVE TO DRIVING A CAR 10,000 MILES
1. 3 MM jumps in 2010 fatalities 21 — .00007%.
2. Risk of dying in a car accident for each 10,000 miles driven: .0167%
3. Conclusion: 24X more dangerous to drive 10,000 miles in a car.
TYPICAL SAFETY PRECAUTIONS
1. In the US law requires a reserve parachute.
2. Many countries also require use of an automatic activation device (AAD) which “opens the reserve parachute at a pre-determined altitude if it detects that the skydiver is still in free fall.”
3. Solo-parachuting usually requires 4 to 8 hours of ground training in order to master the “proper parachute landing fall” (PLF) which is all about dispersing “ the impact through flexion of several large, insulating muscles (such as the medial gastrocnemius, tibialis anterior, rectus femoris, vastus medialis, biceps femoris, and semitendinosus).”
Please share the coolest thing you learned this week related to sports, dance, fitness. Or the coolest thing you learned about Sports, Dance, of Fitness in your life — whether on the field, on the dance floor or in the gym, whether from a coach, a parent, a friend, or just your own experimentation.
This is your chance to make someone else’s day. Or even change their life. It’s perhaps a chance to put into words something you have never articulated before. And to cement in your own memory something cool you might otherwise forget. Or to think more deeply than otherwise about something dear to your heart.
