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.

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

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

What the air is actually doing

Drag the figure to rotate it, or pick an orientation. The airflow redraws as the body turns. This is the thing coaching is really about — not the shape, but what the shape does to the air.

Firsts

Someone has to go first

A lot of what is now normal in Australian body flight did not exist here until Downunder Dynamics built it. Some of it did not exist anywhere.

Object Boogie

2024 · 11:10

The whole week. Objects built in a shed, thrown out of an aircraft and flown with — kegs, drums, banners, a bomb — plus the people who turned up to do it.

Firsts

Body Piloting

Invented the sport. One-versus-one competitive flying in a vertical wind tunnel — leader and follower in the same column of wind, the follower matching or busting. Ten years and forty thousand dollars of development, now flown as its own category at Australian national level.

Atmonauti at the Nationals

Ran the first Atmonauti competition at the Australian Nationals, putting angle flying in front of the country's competitive scene as a discipline in its own right.

The Object Boogie

The first of its kind: kegs, drums and whatever else can be made to fall predictably, welded and weighted and tested, then thrown out of an aircraft to be flown with.

Coaching camps in Australia

Brought the multi-day coaching camp format to Australian drop zones and tunnels, at a point when serious progression meant going overseas for it.

Records

Head-up world record — Australian captain

Captained the Australian contingent on the 96-way head-up world record at Skydive Arizona, 30 November 2024 — the standing record, and the jump the film at the top of this page was shot on. Big-way record flying is unforgiving: ninety-six people have to be in exactly the right slot at exactly the same moment, and one flyer out of place ends it for everyone.

Head-down world record — the 164-way

One of 164 flyers on the head-down world record over Skydive Chicago in July 2015, which broke a 138-way that had stood since 2012. The 164 then held for a decade before a 174-way took it in 2025.

Competition

Dynamic 4-way

Medalled in D4W — the fastest and least forgiving thing the tunnel has, where a whole team's line has to stay clean at speed.

Australian Nationals

Multiple national medals across gold, silver and bronze, over several years and more than one discipline.

Recognition

APF Tim Bates Award

Awarded by the Australian Parachute Federation for contribution to the sport.

APF Achievement Award

Recognition from the governing body, alongside work on coaching events, regulation amendments, educational resources and coaching programs.

Reach

First Australian skydiving channel

The first Australian in the sport to build a YouTube channel properly — now past six thousand subscribers with hundreds of videos, a lot of it educational material given away rather than sold.

Online coaching, anywhere

Footage in, analysis and a plan back out, with no location constraint. Coaching that does not require you to live near a good tunnel.

Mentoring the next generation

Bringing on the coaches and competitors who come next, which is the part that outlasts any individual result.

The approach

Why people plateau

The symptom isn't the cause

A leg that won't stay put might be a mechanical limit, a habit built in your first fifty jumps, or a spatial awareness gap. Those need three different fixes, and treating all of them as "arch harder" is why people stall for years.

Mechanics before positions

Copying a shape gets you a shape. Understanding what the air is doing to your body, and what your body is doing back, gets you something you can adapt when conditions change.

The head is part of the airframe

Plenty of flyers are physically capable of a move their nervous system won't let them commit to. That's a coaching problem, not a character flaw, and it's addressed directly rather than talked around.

Built around your goal

If it's a competition, we work backwards from the competition. If it's flying safely with your mates, we work on that instead. There's no fixed syllabus you get marched through.

Who's behind it

Mason Corby

Both coaches

Over 14,000 jumps since 2006 and more than 12,000 hours in the wind tunnel. World record holder, Atmonauti Instructor-Master Navigator No. 18, IBA Level 4 tunnel instructor, aerial display performer and Australian Army veteran.

Mason founded the Body Piloting Championships, now flown as its own category at Australian national level, and has worked alongside the Australian Parachute Federation on coaching events, regulation amendments and sport development.

That background matters for one reason: the coaching comes from someone who has had to solve these problems under real pressure, not someone repeating a syllabus.

Mason coaches in the tunnel and the sky across every level and discipline. His brother Harry, an instructor at iFLY Downunder, coaches in the tunnel from $300 an hour.
