# Frequently Asked Question

### Can we be space sick?

###

Space sickness is a kind of motion sickness that can occur when one's surroundings visually appear to be in motion, but without a corresponding sense of bodily motion. This incongruous condition can occur during space travel when changes in g-forces compromise one's spatial orientation. It typically doesn't come up until you've gone through several rounds of zero-G.

### Can you swim in zero G?

###

You can sort of swim, but it would be very slow. The viscosity of air vs water is very low. Therefore the 'scoop' your hands or feet can get of the fluid, to propel it, and thus move you around would need to be much higher. If you had fans (or 'wings') on your arms you would be more effective.

### Is there a lower/upper age limit for passengers on an Air Zero G flight?

###

You need to be at least 18 years old to take a gravity-free flight. There is no upper age limit. Health is the most important deciding factor. Several 70-year-olds have already taken our flight and there is no reason why someone older than that should not fly. However, some flights are open at the age of 14 years old.

### Are there medical conditions that prevent someone from taking a parabolic flight?

###

People with certain diseases or medical conditions are advised not to take a parabolic flight. Be sure to have a medical examination before.

### How can you prepare for your gravity-free flight?

###

There is no preparation required in terms of your physical condition or fitness. The most important thing is to return the requested documents (data form and medical certificate) within the agreed time period.
Get a good night’s sleep the day before your flight and eat a regular breakfast before you arrive. As you will be provided with a flying suit and shoes, you do not have to bring any special clothing.
If you wear glasses and they do not slip down your nose when you lower your head, do not worry: you will not lose them during the flight. Otherwise you can use a lanyard or leave them on the floor.oui mais il ya des truc contre

### What are the safety guidelines when flying on board the Air Zero G?

###

The most important safety guidelines are the following:

- Stay seated with your seatbelt attached during takeoff and landing
- Listen to the cockpit announcements alerting you to the hypergravity phases, and the beginning and end of the gravity-free phases, in order to return to the floor in an appropriate position
- void sudden or random movements that might injure other passengers (such as kicking your legs)
- Follow all the instructions you are given during the briefing and by the instructors and flight safety officers on board

### Does it need physical condition?

###

You don’t need to be an Olympic athlete! You just have to be reasonably fit. For example, you should be able to climb two flights of stairs without getting out of breath.

### Will I be scared during the flight?

###

Lying on a foam mat, you will just feel the effect of the acceleration. Your body will weigh almost twice its normal weight, as if someone were lying on top of you for twenty seconds. Nor will you slide down the cabin like a mountaineer down a rockface. Your body will simply be held down to the mat. During the periods of weightlessness, the sensation of floating is so surprising that you will hear cries of joy and amazement throughout the aircraft. The parabolas always end with applause and laughter.

### What is the carbon footprint of Air Zero G flights?

###

The emissions of all flights operated by Zero G, including scientific research flights, are offset by voluntary technology investments in developing countries, delivering reductions in excess of our emissions.
