Quick answer: iFly is substantially safer than real skydiving — there’s no parachute, no aircraft, no altitude, and the wind tunnel is enclosed in a controlled environment. The most common injuries are minor shoulder strains and bruised egos, not serious harm. Catastrophic injuries are rare. The biggest risks are: (1) flyers with prior shoulder, neck, or back conditions ignoring screening, (2) ignoring instructor signals, and (3) loose items in pockets becoming projectiles. If you’re physically healthy and follow instructions, the risk is comparable to a typical theme park ride.

This guide covers what actually happens to your body in the tunnel, the documented risks, what iFly does to keep you safe, and the situations where you should think twice.


How indoor skydiving compares to real skydiving

The first thing to clear up: indoor skydiving is not skydiving. There’s no parachute. No plane. No altitude. No malfunction risk. The “skydiving” name is about the body position and the sensation of freefall, not the activity profile.

Real skydivingiFly indoor skydiving

iFly’s risk profile is closer to a gymnastics class with a coach than to skydiving.


What actually happens to your body

The wind speed

iFly’s wind tunnel runs at roughly 100–120 mph for First-Time Flyers. That’s enough to lift a 150–200 lb person off the floor and keep them airborne. It’s not painful, but it is loud (hence the helmet/earplugs), and your skin and clothes will flap noticeably.

The body position

Standard tunnel position:

  • Face down, looking forward
  • Slight arch in the back (“belly to the wind”)
  • Arms forward, slightly bent, palms down
  • Legs spread at ~45 degrees, slight bend at knees, toes pointed

This position is what keeps you stable and lifted. The instructor will adjust you in real time using hand signals and gentle physical guidance.

The G-forces

Wind tunnel flying produces roughly 1G of force in steady flight — the same as standing on the ground. You don’t feel “G-forces” the way you would on a roller coaster. The sensation is more like floating on a strong, steady wind.


Documented risks (the honest list)

Minor (most common)

  • Sore shoulders or neck for a day or two after — your shoulders work harder than usual
  • Bruised forearms or knees from accidentally bumping the tunnel walls
  • Mild headache from ear pressure changes (rare, helmet-related)
  • Flushed face or red marks on cheeks from the wind (cosmetic)

Moderate (uncommon)

  • Shoulder dislocation in flyers with previous dislocations who didn’t disclose at booking
  • Lower-back strain in flyers who arch too aggressively
  • Sprained wrist from incorrect arm positioning
  • Eye irritation from wind getting around poorly-fitted goggles

Serious (rare)

  • Hard contact with tunnel walls in flyers who lose body position completely (instructor catches most of these)
  • Significant shoulder or rotator cuff injury in pre-existing conditions
  • Cardiac events in undiagnosed heart conditions

Truly catastrophic (extremely rare)

iFly’s overall safety record across millions of flights since the company started is excellent compared to virtually any adventure activity. Catastrophic injuries are rare enough that they make news when they happen.


What iFly does to keep you safe

Pre-flight screening

Every flyer fills out a waiver covering:

  • Pregnancy
  • Recent surgery or active injuries
  • Heart conditions
  • Shoulder/neck/back issues
  • Weight against location-specific limits

The screening matters. Lying or omitting on the waiver is the #1 driver of avoidable injuries. See our age & weight requirements guide for the full screening list.

Required gear

  • Helmet — protects against bumping the tunnel wall and reduces ear noise
  • Goggles — keep wind out of your eyes (wind at 120 mph dries them out instantly)
  • Earplugs — provided; the tunnel is loud
  • Flight suit — provided in some markets; reduces wind drag and gives the instructor something to grip
  • Lace-up athletic shoes — required; they don’t fly off

Instructor presence

A trained instructor is inside the tunnel with you for the entire First-Time Flyer experience. They:

  • Catch you if you lose position
  • Adjust your body in real time using hand signals
  • Reduce wind speed via communication with the tunnel operator if needed
  • Keep you off the walls

The instructor is the single most important safety element. They’ve flown tens of thousands of hours.

Tunnel design

Modern iFly tunnels include:

  • Padded walls and floor so impacts don’t cause hard injury
  • Adjustable wind speed controlled by a tunnel operator
  • Emergency stop that kills the wind in seconds
  • Glass viewing area for spotters and instructors

Limited flight duration

A First-Time Flyer flight is roughly 1 minute (60 seconds), then the next person flies. This is short enough that fatigue doesn’t compound — most injuries in any activity happen when people get tired.


When you should think twice (or not fly)

Do not fly if:

  • You are pregnant at any stage
  • You had recent surgery (within ~12 months without doctor’s clearance)
  • You have an active dislocation of any joint
  • You have severe heart conditions without doctor’s clearance
  • You had a recent concussion (within 6 months without clearance)

Call ahead before booking if:

  • History of shoulder dislocation (the body position stresses shoulders)
  • Neck or back injuries (flexion is part of the position)
  • Heart condition or pacemaker
  • Epilepsy or seizure disorder
  • Recent eye surgery (LASIK, cataract within ~3 months)

Be honest at the waiver

The waiver isn’t a formality. iFly has decades of data on which conditions cause issues. If you’re unsure about your eligibility, call ahead and explain your situation. They’ll give you a clear answer.



Frequently asked questions

Has anyone died at iFly?

Catastrophic injuries are extremely rare across the industry given the volume of flights. The activity is much safer than real skydiving or many other adventure sports.

What’s the most common injury?

Sore shoulders the next day — about as common as the soreness after a tough workout. Most flyers report no injury at all.

Can the wind tunnel malfunction?

Tunnels have multiple redundant systems and emergency stops. The wind can be cut in seconds if something goes wrong.

What if I panic in the tunnel?

The instructor is right next to you. They’ll see your panic immediately and signal the tunnel operator to slow or stop the wind. This is part of why the instructor is in the tunnel with you — most outdoor adventure activities don’t have that luxury.

Is iFly safe for kids?

Yes — within iFly’s age limits (3+ at most locations) and with adult supervision. Kids fly the same length as adults and are typically given more instructor support. See our age & weight requirements guide for the full breakdown.

Is iFly safe for seniors?

Yes if your health screening is clear. iFly is popular with active retirees. The constraint is health, not age.

Can I get hurt by the wind itself?

The wind speed (~100–120 mph) is well within human tolerance. People don’t get “windburn” from a 1-minute flight. Your eyes will dry out without goggles, your face will look flushed for a few minutes after, and that’s about it.

What if I have a shoulder issue?

If recent or active: don’t fly. If old and fully healed: call ahead. The body position with arms forward stresses shoulders, and old injuries can flare. Be honest at the waiver.

Is iFly safer than skydiving?

Yes — substantially. No parachute, no altitude, no aircraft, no weather. The activity profile is closer to a controlled gymnastics environment than to real skydiving. See our iFly vs real skydiving guide for the full comparison.

Do I need to sign a waiver?

Yes. It’s standard for any wind tunnel facility. Read it — it’s the formal version of the screening list above.

What if I have a panic attack in the tunnel?

Wave the instructor — they’re trained for this and will signal the operator to stop the wind. You’ll be back on the floor in seconds. People with anxiety often do iFly successfully because the instructor is right there with you.


Bottom line

iFly is one of the safer “adventure” activities you can do. The risk profile is closer to a controlled fitness class than to extreme sports. The biggest risks are health conditions you fail to disclose — not the activity itself.

If you’re physically healthy and willing to follow instructor signals, you’re going to have a great time and walk out fine.
