How I built a jet suit

Michael Browning:

engineer,

innovator --

inventor really,

and inspiring father.

He had a passion for flight,

as you can kind of sense

from that rather dubious
1970s [office-leaving present,]

and some 40 years after that was created,

a small group of us got together

to have a go --

a run at the whole challenge of flight
that inspired people for years,

and do it in a very different kind of way.

And that's the journey I'd like
to share with you now.

The starting hypothesis was one
of the human mind and body --

as you've seen for the last few days here,

is an amazing construct --

and what if you augmented
that wonderful machine

with just the right technology?

If you approach flight
in that kind of [real] way,

where could you get to?

So my training partner here
back in London --

[Denton] --

is doing a much better job
of that kind of stuff than me.

[Guess what, it's London].

The idea was that you augment that.

And so, how do you augment that?

Well, we bought one of these.

So this is a [microgas] turbine.

This was ground zero.

That little piece of gear proved
really quite impressive,

so we got two in a field.

The real hero here is the little --

right in the background --

there's a lady tending some vegetables.

She does a brilliant job
of trying to ignore us for a while --

(Laughter)

I think the only thing
less happy is the grass

that we did probably damage quite badly.

You get an idea of the thrust here
where I try to hold them horizontally

and somewhat fail.

That's around 50 kilos of thrust there.

So we were quite impressed with that.

We thought we were getting somewhere.

So there's only one sensible way
to go from there ...

you get four.

(Laughter)

I [.... a lot] watching these back.

So, then we thought well, let's try
and spread the load a bit,

you know the legs are designed
to take the load,

so why do we spread it out a bit?

That bit was good.

The harness --

a nice idea but it didn't really work,

as you'll see now.

This whole journey was very much
about trying things --

(Laughter)

Yeah, it really didn't work.

Trying things and learning
by failing at them most of the time.

And that included failing by falling over.

If you notice,

we've got five engines here --

not to be put off by the fact
one was in [maintenance slow go],

and then I --

(Laughter)

And then I pinched a fuel line.

So again, good learning,

we learned not to do that again.

This was a blind alley.

(Laughter)

This was three on each arm --

that was ridiculous.

That was 70 kilos on each arm.

Again, struck that one off.

(Laughter)

But we, you know, we were starting to make
some really quite convincing progress,

just enough to make you believe
that maybe --

maybe we could get there.

You can see,

look --

tantalizing.

And the model of one on each leg
and two on each arm,

on paper that was enough thrust.

And then we did what
I'm about to show you now,

and I still love watching this one.

This was our first six second,
reasonably coherent flight.

(Applause)

That was the point where this
endeavor went from

"I'm really not sure
this is going to work,"

to "Oh my god, it does work."

And from there on we then refined it,

but we carried on falling over a lot.

Falling over, like I say, is definitely
the best way to learn.

And after a while we starting
re-refining the layout of all of this.

You'll see,

I mean, that's stability and control,

there's no wires there or anything,

that's a combination of us
refining the technology,

including the tupperwear box
on the back for the electronics --

nice step --

and actually learning
the balance and control.

I'm now going to save your ears
for the next short piece

and talk over it,

because after a while the jet engine
noise is a bit annoying.

As you see hear,

this is only a few weeks ago.

You can see the stability and control
is really quite nice,

and I'd like to think this somewhat
validates that starting hypothesis

that the human mind and body,

if properly augmented in that way,

can achieve some pretty cool stuff.

I mean, look I say,

I'm not looking at --

I'm not thinking about where I'm moving
my arms at that stage.

I'm look at the objective
of where I want to get to,

and a bit like riding a bike,

my arms are just doing their thing.

It's a very strange experience.

So where is all this headed?

I'll talk over this landing --

I think I land in this one.

I don't think anybody's going to
get out of Walmart

or taking the kids in school in any
of this stuff for a while,

but the team at Gravity are building
some awesome technology

that's going to make
this look like child's play.

We're working on some things

that are going to seek to bring
this pretty unusual experience of flight

to a wider audience,

beyond the events
and displays we're doing.

And we're even starting to look
for Pilot Two and Three,

so if there's any volunteers ...

And I've got this vision,

and it's going to sound audacious,

but hey, let's just stick it out there --

that one day maybe we can,

you know, rise up above a beach,

fly up and down the coastline of it,

rise up a little bit higher

with some of the safety kit we're
working on to make this achievable,

and then low over the horizon
comes a Hercules with a ramp down,

and as it comes past you,

you then start picking up speed
and see if we can intercept --

from the rear, not from the front,
that would be a mistake --

and then try and land in the back.

That's a little way off at the moment.

But this is also,

if I take a big step back from this,

this is also a very
personal journey for me.

Back to that lovely photo,

or photo in a picture.

Sadly, my father took his own life
when I was 15,

and left an awful lot
of unfulfilled ambition.

He was a wonderful inventor,

maverick --

creator.

And I'd just like to think

if it was possible,

if he was looking down,

he would be --

he'd certainly be smiling at some
of the things we've gone and done

I think here.

So, it's really a tribute to him.

Thank you very much.

(Applause)

I'm probably more nervous about
doing the demo straight after this,

so yeah,

I've got a lot of things
to get done today.

The worst case scenario:

we don't get a clean start,

or we get an unplanned failure
while I'm actually flying around,

but this is why we keep it very low,

so the worst is I just look like an idiot
and fall on my own rear,

as they say.

So you can all enjoy that if that happens.
