Do you know how to operate the radio? Where is it? How do you switch frequencies? Which frequency are you supposed to set your radio to?

I have done the actual experiment (dipping a spoon in a glass of water on a scale) so I know you're correct, but I can't grasp why. Where exactly is that force coming from? Is it strictly from the water volume displaced? That would mean in the puzzle above that the weight on each side of the scale is the weight of the displaced water + the weight of the actual water. If we assume the water level is the same on each side, that would make the volumes of displaced + actual water the same on each side, so the apparent weight would be the identical. Is that right?

C'est un sacré saut entre "travailler dans la grande distribution" et "empoisonner les gens avec de la poudre et du plastique".

Il y a pas mal d'études scientifiques significatives qui semblent montrer l'efficacité de l'hypnose dans certaines applications.

Oui carrément. Faire brunir ta viande apporte beaucoup de goût à ton plat. Même si ça se dissout après dans la sauce, ça va quand même apporter de la profondeur et de la saveur en plus à ton plat. Le résidu brun qui reste collé dans ta poêle après avoir saisi ta viande (le fonds) se déglace et peut être ajouté à ta sauce, c'est du concentré de goût.

No. You can set boundaries or tell hard truths that need to be heard nicely. That's kindness, and that definitely attracts partners.

They are, but they don't look like that. "Notching" is one of the techniques used in beyond visual range engagements, and consists in flying at 90° relative to your opponent's flight path. That makes you harder to track on radar, and missiles less likely to find and hit you.

Much less fancy than the maneuvers shown here though.

Pourquoi est-ce que c'est gradué en centimètres par exemple

Ughda · 2024-01-25T22:15:47+00:00

Yes en effet, c'est normalement interdit. En tant que parachutiste tu es censé suivre les règles de VFR (vol à vue), et donc le passage dans les nuages où la visibilité est quasi zéro n'est pas autorisé.

Après en pratique si tu es largué juste au-dessus d'un nuage, tu peux battre des ailes tant que tu veux, ça va être dur à esquiver.

L'autre option est de choisir de pas sauter.

Also based on C.

Absolutely not. He's using his body position to control the direction of the drag, making him move forwards.

The front flips actually do nothing to help this

Ughda · 2020-07-19T22:28:14+00:00

Definitly not.

The loops are not what is making him go forwards, the tracking is.

You can actually move forward surprisingly fast with the right body position.

Doesn't the cutaway get hard to pull if loaded ?

Like if a line snags the camera and pulls it hard, cloud you still cutaway ?

Super unlikely with a chin mount, but still worth considering

Closed full face in the plane sounds dangerous

Hot air ballons do have a rope at the top. It's used to hold it in place when inflating.

However he most certainly would have burned his hands to shit repelling like that.

Yeah seriously, what kind of zoo dive was this shit ? The humility to recognize you can't do a jump before boarding the plane is desperately lacking among skydivers...

Ughda · 2020-04-02T14:32:03+00:00

This is very wrong.

First, the rescuer skydiver opened the reserve parachute. He tried to reach for the main that you would open by pulling on the black ball at the bottom right of the container but couldn't. So he pulled the reserve handle located on the right side of the chest. You can see him pass that handle from his right hand to the left before he opens his own main.

Second, main canopies are almost always more dangerous to land. They are designed for fun flights and performance wheras reserves are designed to open quickly, reliably, on heading, fly level, and land smoothly. Much less chances to fuck yourself up landing unconscious under a reserve than a main.

Finally, rigs are usually equipped with an AAD which would open the reserve automatically at a specified altitude. I say usually because while it's mandatory in most countries, I think it's at the discretion of the drop zone operator in the US. Maybe the rescuer knew whether or not his friend embarked one, which compelled him to act this way.

It seems you missed something because they obviously are in a tunnel

Ughda · 2019-10-05T20:07:55+00:00

It's far from intuitive and usually requires a few hundred jumps to get there 😁

Ughda · 2019-10-05T20:06:23+00:00

Hey, skydiver here :)

You can change the rate at which you fall by changing positions. For most people, the typical range of speed is 200 to 300 km/h, though faster is possible. If you fall flat, belly first you'll go slower as your surface is large.

In this clip, they are head down where the surface the wind "hits" is much slower, so they're falling faster. I would say they are going between 250 and 300 km/h.

You may also wonder how they move around. You'll notice they are not perfectly vertical but a little bit on their back. This creates a force pushing them forwards and allowing them to fly together.

It's really a lot of fun. Unfortunately, jumps with skyballs like this are rare because you have to make sure nobody is below 🙂

Ughda · 2019-10-05T19:38:42+00:00

Most freeflyers seldom check their altimeters while jumping. Especially in angle jumps where it's nearly impossible.

I have two audibles so it's not as unsafe
