Skydiving · Wind tunnel · Body flight

Fly like you understand the air.

Most coaching tells you what you're doing wrong. That's the easy part, it's on the video. The work is figuring out why, so the fix holds after the coach goes home.

Who's behind it

Mason Corby

Australian Army veteran. More than 14,000 skydives, 12,000 hours in the wind tunnel and 250 BASE jumps. World record holder, X Games gold medallist, and the APF's Outstanding Skydiver of the Year (the Tim Bates Award), as well as an APF Service Award recipient.

He invented Body Piloting, created Foot Fetish, the world's first head-up-only skydiving event, and the Object Boogie. Fifteen years, more than 500 camps and 30 Train-the-Trainer courses later, the coaching comes from someone who has solved these problems under real pressure, not someone repeating a syllabus.

Humans can't fly. What we do is learn to feel something invisible and push off it. That's not a sport skill, that's a sense you weren't born with, and it takes time to grow one.

What's on offer

Coaching

All options

In person · by the hour

Tunnel coaching

One-on-one or small group coaching in the tunnel. Body position is the surface problem; the work is in mechanics, airflow and what your brain is doing under load.

Session planned around your actual goal, not a syllabus
In-tunnel correction and immediate video debrief
Body mechanics and aerodynamics explained, not just copied
Mental preparation and spatial awareness work

Any level, any discipline, belly, freefly, angles, dynamic

From $300 AUD / hourMason $400 · Harry $300 · tunnel time booked separately Book now

Remote · video review

Online coaching

Send footage and get a read on your body, not a general lesson. What your faults actually are, why your anatomy produces them, and the fix that suits you rather than the one in the syllabus.

Frame-by-frame analysis of your flying, not a general impression
The cause identified, not just the symptom named
Corrections matched to your build, your habits and your old injuries
Drills for your next tunnel or jump session
Freefly, belly, angles, dynamic, canopy control or competition prep

Anyone who has been told what they are doing wrong and still cannot fix it

Coach development

For flyers moving from being good in the air to being able to teach it. Teaching someone to fly is a different skill from flying, and most people are never taught it.

How to diagnose a fault rather than describe a symptom
Briefing and debriefing that actually changes behaviour
Managing risk and progression across skill levels
Building a coaching pathway you can run yourself

Experienced flyers moving into instruction

If you're working hard, you're doing it wrong. You're not pushing yourself through the sky, you're presenting a shape and letting the sky push you. Effort is the fault, not the fix.

The app I'm building for the whole sport

Every freefall discipline, sky and tunnel, and everyone in it: flyers, coaches, drop zones, wind tunnels, event organisers and judges. Loads, spotting, logbooks, coaching, competition and rankings on one system. Founding members are already in.

The air, actually

Here is the thing you cannot see

Every coach can tell you your leg is out. This shows you what that leg is doing to the air, a real fluid simulation, not an animation. Move the flyer, change the angle, draw your own shape and watch the airflow rebuild around it.

Works best with a mouse or on a tablet. Open it full screen

Downunder Dynamics #11

The rumours were wrong.

Coming soon

DD10 was billed as the last one for some time. It was. Now the series that built freeflying in this country is coming back, and it's coming back better than ever.

Started in 2015 to prove Australian coaching could stand next to anything overseas
DD3 put around 80 jumpers and 15 coaches in the sky, 32 loads in a single day, night load included
Sold out within hours, more than once
DD10 went invite-only: fewer coaches, harder jumps

Foot Fetish #5

Head up or beer.

Coming soon

The world's first head-up-only skydiving event. After #4 the word was that it was done. It isn't. Fifth edition, and the bar has never been higher.

The first event anywhere built entirely around head-up flying
#4 at Byron Bay flew the first 7-way head-up round out of a Caravan side door
Static head-up, and turning head-down formations into head-up ones
Go head down to save it, you buy the round

The load walking out to the aircraft — Object Boogie 2024

Your flying, read properly.

In the tunnel, in the sky or from your footage. Pick a time and we'll work out what's actually holding you back.
