@endorse80 Certes je n'étais pas très bon en physique, mais je comprends quand même, l'interaction des forces et surtout le matériel et les techniques utilisées dans ce sport... Je trouve que c'est très bien que tu aies sauté, mais sache quand même qu'un para qui a quelques sauts de plus que toi sait quand même de quoi il parle ;)
Kiffe bien l'australie, et si tu en as la chance ressaute!

Its seems you are, and I am too. Je vais donc t'expliquer que tu ne tombes pas a 250km/h. Si tu atteignais, une vitesse de 250km/h, le parachute de 300 pieds carrés que ton moniteur a sur son dos s'arracherait immédiatement... Le coefficient de resistance augmente avec le "drogue", le petit balon blanc que ton moniteur déploie dans les 5 secondes de la sortie, reduisant donc ta vitesse a 180/190 km/h. C'est pour ca que les parachutistes solos peuvent suivre un tandem.

are you french?

What's the best state to go skydiving here in the U.S. ?
Terminal velocity is not 250km/h lol

@endorse80 . You are right, likely the terminal velocity was 0km/h on earth! Correction done. Thx.

@sydneysteph @sydneysteph Dude, 50 meters/s equals 180 km/h terminal velocity belly faced down. If the terminal velocity was higher with a tandem explain how cameramen could follow. Funny to see how a dude who has only one tandem jump knows everything on the physics involved in skydiving....Been skydiving for 6 years man....
blue skies to you!

@endorse80 At least you are funny!
Thanks to you I reopened my dusty physics book.
You are right, the terminal velocity of a 75kg skydiver is probably around 50m/s (180km/h) bellyface down. As you are surely aware (been skydiving for 6 years and very good at physics) the weight plays a significant role in determining the terminal velocity. I am in a tandem (we probably weight around 150km together), therefore our terminal velocity is more than 180km/h.

@endorse80
If there was a cameraman with us he would be slower than us. We are not diving with a supplementary cameraman, we were using a camera with a wide angle lens in the left hand of the instructor (Please don’t ask me to explain to you the physics about lens and focal length)
Thank you for your interest and your attention to detail.
