every this looks so beautiful from space. would make a nice wallpaper to.

Woah! Imagine skydiving in that thing!

Chances are 100% you wont live to tell the tale Graal. Unless you have some MDK suit

Or it dies down before I reach it ;)

14 minutes is roughly the maximum time you have to free fall, so there is a slim chance... but i wont try it, unless i get promised a nice 3KG steak with some chips and a lekka beer, then maybe.

It's strange how something so destructive can have such a beauty to it.

Not really. Many thing can be destructive and be beautiful (Black Hole/Nuke/Fire/TV/Dragons).
But then beauty is a matter of opinion too (like the list above).

Me love these pics much.

EDit: O wait...

Well the average diameter of the eye for a Hurricane/Tropical Cyclone is 50km, where there are little to no winds and its pretty calm. The height the of clouds around the eye is between 10-14km. Terminal velocity for a skydiver of 100KG, assuming acceleration due to gravity is 9.81m/s^2, is 54m/s, if he chooses to make his aerodynamic cross-section smaller, his velocity will increase to roughly, 100m/s, so he can dive the 13km in roughly 3 minutes, giving him time to reach terminal velocity. Opening his chute, would take him another 2-4 minutes to touch the ground.

Physics lesson concluded. ;)

Theoretically and practically it is possible, but the practicality of actually attempting is going to be difficult to achieve.

it's a pure beauty in space :O

+ that pic is taken 354km above the earth, so it will take 1h20min to fall from that height?

Um, we are skydiving through the eye, not through the Ionosphere, Mesosphere & Stratosphere, just the Troposphere. Also you won't exactly be able to "skydive" from 354km from Earth, as you would burn up once you hit the Ionosphere.

The Earth "stops" experiencing weather above the Tropopause, the layer of air dividing the Stratosphere & Troposphere, hence why most commercial airliners fly just under the Stratosphere.

thanks for that, but it would be frikken cool if you could don't you agree?

Irrelevant. His acceleration would be the same whether he is 1kg or 1000kg.

His surface area makes a difference, but you've already mentioned that.

Doh, explains why I failed fluid dynamics in my physics exam. ;)

A few pics slightly bigger then the ones posted (http://images.google.co.za/images?q=hurricanes+from+space&gbv=2&hl=en&sa=G&imgsz=huge)
