and that s why we can hardly hear anything. system is supersonic. if this were full of air, we d get a sonic boom on every single revolution. you can hear a little bit. can you hear it? just a little bit. a little bit of vibration too. arming system. here we go. so he s doing the launch sequence now. ten. nine, here we go. ..seven, six, five, four, three, two, one. launching. whoa! that was it. applause yeah! decelerating system. in my mind, this has gone from nonsense to plausible in the space of a few hours. and in october last year, the first test launch in new mexico proved that the carbon fibre dart could not only launch, but also survive a landing in which it buried itself in the desert. that was going supersonic straight towards us. yeah! and then it went round. and then it came towards us again.
single revolution. you can hear a little bit. can single revolution. you can hear a little bit. can you single revolution. you can hear a little bit. can you hear- single revolution. you can hear a little bit. can you hear it? - a little bit. can you hear it? just a a little bit. can you hear it? just a little a little bit. can you hear it? just a little bit? a little bit. can you hear it? just a little bit? a a little bit. can you hear it? just a little bit? a little - a little bit. can you hear it? just a little bit? a little bit| just a little bit? a little bit of vibration. here we go. he is doinu of vibration. here we go. he is doing the of vibration. here we go. he is doing the launch of vibration. here we go. he is doing the launch sequence - of vibration. here we go. he is. doing the launch sequence now. ten doing the launch sequence now. ten. . doing the launch sequence now. ten. , , ten. nine, eight, seven, six, five, ten. nine, eight, seven, six, five. four.
so this mostly turns to dust as it hits the end of the tunnel. oh, my gosh. dramatic music now, where were we? oh, yeah! 500 miles an hour. so now you re going about as fast as a jet. the actual projectiles and the spinning arm are made of carbon fibre pretty much the only substance that can withstand the forces involved. 700 miles an hour. and in order to spin up to nearly 1,000 miles an hour today, this entire chamber needs to be a near vacuum, and that s why we can hardly hear anything. system is supersonic. if this were full of air, we d get a sonic boom on every single revolution. you can hear a little bit. can you hear it? just a little bit? a little bit of vibration too. arming system. here we go. so he s doing the launch sequence now. ten. nine, here we go.
