00:00:01,312 --> 00:00:03,954
Michael Browning: engineer,

2
00:00:03,978 --> 00:00:05,538
innovator --

3
00:00:05,562 --> 00:00:06,751
inventor, really --

4
00:00:06,775 --> 00:00:08,014
and inspiring father.

5
00:00:08,594 --> 00:00:11,142
He had a passion for flight,
as you can kind of sense

6
00:00:11,166 --> 00:00:15,178
from that rather dubious
1970s office-leaving present.

7
00:00:15,691 --> 00:00:18,502
And some 40 years after that was created,

8
00:00:18,526 --> 00:00:20,093
a small group of us got together

9
00:00:21,140 --> 00:00:22,297
to have a go,

10
00:00:22,321 --> 00:00:26,678
a run at the whole challenge of flight
that inspired people for years,

11
00:00:26,702 --> 00:00:28,759
and do it in a very different kind of way.

12
00:00:28,783 --> 00:00:31,468
And that's the journey I'd like
to share with you now.

13
00:00:31,492 --> 00:00:34,710
The starting hypothesis was one
of the human mind and body,

14
00:00:34,734 --> 00:00:37,128
which, as you've seen
for the last few days here,

15
00:00:37,152 --> 00:00:38,971
is an amazing construct.

16
00:00:38,995 --> 00:00:42,661
What if you augmented
that wonderful machine

17
00:00:42,685 --> 00:00:44,163
with just the right technology?

18
00:00:44,187 --> 00:00:46,522
If you approach flight
in that kind of real way,

19
00:00:46,546 --> 00:00:47,798
where could you get to?

20
00:00:47,822 --> 00:00:51,189
So my training partner here
back in London, Denton,

21
00:00:51,213 --> 00:00:54,217
is doing a much better job
of that kind of stuff than me.

22
00:00:54,241 --> 00:00:55,901
Guess what? It's London.

23
00:00:55,925 --> 00:00:58,589
The idea was that you augment that.

24
00:00:58,613 --> 00:01:00,167
And so, how do you augment that?

25
00:01:00,191 --> 00:01:01,685
Well, we bought one of these.

26
00:01:03,216 --> 00:01:05,127
This is a micro gas turbine.

27
00:01:05,670 --> 00:01:07,768
This was ground zero,

28
00:01:07,792 --> 00:01:10,941
so that little piece of kit
proved really quite impressive,

29
00:01:10,965 --> 00:01:12,877
so we got two in a field.

30
00:01:14,750 --> 00:01:17,851
The real hero here, by the way,
is, right in the background,

31
00:01:17,875 --> 00:01:19,784
there's a lady tending some vegetables,

32
00:01:19,808 --> 00:01:22,825
who does a brilliant job
of trying to ignore us for a while --

33
00:01:22,849 --> 00:01:24,664
(Laughter)

34
00:01:25,829 --> 00:01:28,234
I think the only thing
less happy is the grass,

35
00:01:28,258 --> 00:01:30,710
that we did probably damage quite badly.

36
00:01:30,734 --> 00:01:32,420
You get an idea of the thrust here,

37
00:01:32,444 --> 00:01:35,070
when I try to hold them horizontally
and somewhat fail.

38
00:01:35,094 --> 00:01:36,968
That's around 50 kilos of thrust there.

39
00:01:37,402 --> 00:01:39,071
We were quite impressed with that.

40
00:01:39,095 --> 00:01:40,937
We thought we were getting somewhere.

41
00:01:40,961 --> 00:01:43,498
So there's only one sensible way
to go from there:

42
00:01:44,393 --> 00:01:45,563
you get four.

43
00:01:45,587 --> 00:01:47,444
(Laughter)

44
00:01:50,798 --> 00:01:53,054
I have to say, I still like
watching these back.

45
00:01:53,078 --> 00:01:56,083
So then we thought well, let's try
and spread the load a bit.

46
00:01:56,107 --> 00:01:57,999
The legs are designed to take the load,

47
00:01:58,023 --> 00:01:59,982
so why don't we spread it out a bit?

48
00:02:00,975 --> 00:02:02,538
That bit was good.

49
00:02:03,014 --> 00:02:04,397
The harness --

50
00:02:04,421 --> 00:02:06,322
a nice idea but it didn't really work,

51
00:02:06,346 --> 00:02:07,802
as you'll see now.

52
00:02:08,112 --> 00:02:10,874
This whole journey was very much
about trying things --

53
00:02:10,898 --> 00:02:11,972
(Laughter)

54
00:02:11,996 --> 00:02:13,795
Yeah, it really didn't work, did it?

55
00:02:13,819 --> 00:02:17,571
Trying things and learning
by failing at them most of the time.

56
00:02:17,595 --> 00:02:21,956
And that included failing by falling over.

57
00:02:22,742 --> 00:02:25,027
If you notice, we've got
five engines here --

58
00:02:25,051 --> 00:02:27,614
not to be put off by the fact
one was in maintenance,

59
00:02:27,638 --> 00:02:28,793
still had a go.

60
00:02:28,817 --> 00:02:29,824
(Laughter)

61
00:02:29,848 --> 00:02:32,511
And then I pinched a fuel line.

62
00:02:32,535 --> 00:02:35,261
So again, good learning.
We learned not to do that again.

63
00:02:35,285 --> 00:02:36,485
This was a blind alley.

64
00:02:36,509 --> 00:02:37,536
(Laughter)

65
00:02:37,560 --> 00:02:39,121
This was three on each arm --

66
00:02:39,145 --> 00:02:40,311
that was ridiculous.

67
00:02:40,335 --> 00:02:42,296
That was 70 kilos on each arm.

68
00:02:42,320 --> 00:02:43,913
Again, struck that one off.

69
00:02:43,937 --> 00:02:45,584
(Laughter)

70
00:02:45,608 --> 00:02:49,070
But we were starting to make
some really quite convincing progress,

71
00:02:49,094 --> 00:02:51,428
just enough to make you
believe that maybe --

72
00:02:51,452 --> 00:02:52,757
maybe we could get there.

73
00:02:53,398 --> 00:02:55,107
You can see, look -- tantalizing.

74
00:02:55,587 --> 00:02:59,436
The model of one on each leg
and two on each arm,

75
00:02:59,460 --> 00:03:01,170
on paper, that was enough thrust.

76
00:03:01,711 --> 00:03:04,844
And then we did what
I'm about to show you now,

77
00:03:04,868 --> 00:03:07,030
and I still love watching this one.

78
00:03:09,612 --> 00:03:14,248
This was our first six-second,
reasonably coherent flight.

79
00:03:15,300 --> 00:03:18,504
(Applause)

80
00:03:19,983 --> 00:03:23,005
That was the point where
this endeavor went from:

81
00:03:23,029 --> 00:03:25,115
"I'm really not sure
this is going to work,"

82
00:03:25,139 --> 00:03:26,640
to: "Oh my god, it does work!"

83
00:03:26,664 --> 00:03:28,259
From there on we then refined it,

84
00:03:28,283 --> 00:03:30,146
but we carried on falling over a lot.

85
00:03:31,093 --> 00:03:34,180
Falling over, like I say, is definitely
the best way to learn.

86
00:03:34,204 --> 00:03:37,902
After a while, we starting
really refining the layout of all of this.

87
00:03:37,926 --> 00:03:40,259
And you'll see,
that's stability and control --

88
00:03:40,283 --> 00:03:42,113
there's no wires there or anything --

89
00:03:42,137 --> 00:03:44,571
that's a combination of us
refining the technology,

90
00:03:44,595 --> 00:03:47,798
including with a Tupperware box
on the back for the electronics

91
00:03:47,822 --> 00:03:50,233
and actually learning
the balance and control.

92
00:03:52,073 --> 00:03:54,726
I'm now going to save your ears
for the next short piece

93
00:03:54,750 --> 00:03:55,909
and talk over it.

94
00:03:55,933 --> 00:03:58,516
After a while, the jet engine
noise is a bit annoying.

95
00:03:58,540 --> 00:03:59,942
This is only a few weeks ago.

96
00:03:59,966 --> 00:04:02,891
You can see the stability and control
is really quite nice,

97
00:04:02,915 --> 00:04:06,365
and I'd like to think this somewhat
validates that starting hypothesis,

98
00:04:06,389 --> 00:04:11,101
that the human mind and body,
if properly augmented in that way,

99
00:04:11,125 --> 00:04:12,911
can achieve some pretty cool stuff.

100
00:04:12,935 --> 00:04:14,508
I mean, like I said:

101
00:04:14,532 --> 00:04:17,496
I'm not thinking about where
I'm moving my arms at that stage.

102
00:04:17,520 --> 00:04:20,554
I'm looking at the objective
of where I want to get to,

103
00:04:20,578 --> 00:04:22,377
and a bit like riding a bike,

104
00:04:22,401 --> 00:04:24,203
my arms are just doing their thing.

105
00:04:24,227 --> 00:04:25,792
It's a very strange experience.

106
00:04:25,816 --> 00:04:27,492
So where is all this headed?

107
00:04:27,516 --> 00:04:29,252
I'll talk over this landing --

108
00:04:29,276 --> 00:04:31,296
I think I land in this one.

109
00:04:31,662 --> 00:04:34,586
Well, I don't think anybody's going
to go down to Walmart

110
00:04:34,610 --> 00:04:37,495
or take the kids to school
in any of this stuff for a while,

111
00:04:37,519 --> 00:04:40,385
but the team at Gravity are building
some awesome technology

112
00:04:40,409 --> 00:04:42,725
that's going to make
this look like child's play.

113
00:04:42,749 --> 00:04:44,098
We're working on some things

114
00:04:44,122 --> 00:04:46,856
that will seek to bring
this unusual experience of flight

115
00:04:46,880 --> 00:04:49,922
to a wider audience, beyond the events
and displays we're doing.

116
00:04:49,946 --> 00:04:52,428
We're even starting to look
for pilots two and three,

117
00:04:52,452 --> 00:04:53,697
if there's any volunteers.

118
00:04:53,721 --> 00:04:54,919
I've got this vision.

119
00:04:54,943 --> 00:04:57,571
It sounds audacious,
but let's just stick it out there,

120
00:04:57,595 --> 00:04:59,873
that one day maybe we can
rise up above a beach,

121
00:04:59,897 --> 00:05:02,619
fly up and down the coastline
of it, rise up a bit higher,

122
00:05:02,643 --> 00:05:05,911
with some of the safety kit
we're working on to make this achievable.

123
00:05:05,935 --> 00:05:08,661
Then over the horizon comes
a Hercules with the ramp down.

124
00:05:08,685 --> 00:05:10,750
As it comes past,
you start picking up speed

125
00:05:10,774 --> 00:05:12,229
and see if we can intercept --

126
00:05:12,253 --> 00:05:14,903
from the rear, not the front,
that would be a mistake --

127
00:05:14,927 --> 00:05:16,561
and then try and land in the back.

128
00:05:16,585 --> 00:05:19,570
And as I say, that's a little
way off at the moment.

129
00:05:19,594 --> 00:05:23,514
But this is also, if I take
a big step back from this,

130
00:05:23,538 --> 00:05:26,125
this is also a very
personal journey for me.

131
00:05:27,352 --> 00:05:29,149
Back to that lovely photo,

132
00:05:29,173 --> 00:05:31,338
or photo in a picture.

133
00:05:31,362 --> 00:05:34,255
Sadly, my father took
his own life when I was 15,

134
00:05:34,279 --> 00:05:37,247
and left an awful lot
of unfulfilled ambition.

135
00:05:37,271 --> 00:05:38,895
He was a wonderful inventor,

136
00:05:38,919 --> 00:05:40,300
a maverick creator.

137
00:05:40,324 --> 00:05:43,266
And I'd just like to think,
if it was possible,

138
00:05:43,290 --> 00:05:44,606
if he was looking down,

139
00:05:44,630 --> 00:05:45,811
he would be --

140
00:05:45,835 --> 00:05:48,852
he'd certainly be smiling at some
of the things we've done here,

141
00:05:48,876 --> 00:05:50,034
I think.

142
00:05:50,058 --> 00:05:51,339
So, it's a tribute to him.

143
00:05:51,363 --> 00:05:52,536
Thank you very much.

144
00:05:52,560 --> 00:05:55,256
(Applause)

145
00:05:56,088 --> 00:05:58,771
(Voice-over) Richard Browning:
I'm probably more nervous

146
00:05:58,795 --> 00:06:00,333
about doing the demo after this.

147
00:06:00,357 --> 00:06:02,377
I've got a lot of things
to get done today.

148
00:06:02,401 --> 00:06:04,690
Worst-case scenario,
we don't get a clean start.

149
00:06:04,714 --> 00:06:07,934
Or we get an unplanned failure
while I'm actually flying around.

150
00:06:07,958 --> 00:06:09,560
This is why we keep it very low,

151
00:06:09,584 --> 00:06:13,071
so the worst is I just look like an idiot
and fall on my rear, as I said.

152
00:06:13,095 --> 00:06:15,106
So you can all enjoy that if that happens.

153
00:06:15,130 --> 00:06:18,439
(Music)

154
00:06:36,174 --> 00:06:38,950
(Jet engine accelerates)

155
00:06:54,399 --> 00:06:56,399
(Cheers)
