But it's still we had two tragic, completely fatal accidents during shuttle.

And

But we've gotten better and better at it.

We've learned so much from each of those problems in the past so that now the vehicle that regularly takes people to the space station and back, the SpaceX Dragon vehicle with a Dragon capsule on top, it's the safest rocket ever.

And that didn't happen accidentally.

It is a natural progression.

And as soon as you make something safe enough and cheap enough, then it stops being just the purview of of a trillionaire like the Soviet Union or the United States.

And it gets down to the billionaire and then the millionaire.

And then I don't know what you call it under that the centenary or something.

Someone who has, I don't know, one hundred thousand dollars or seventy five thousand dollars.

It's still expensive, but if you plot it on a curve, it's easy to extrapolate where it's going.

And that naturally then opens up a lot more commercial opportunity for putting things in space, for satellites to observe the world for commercial purposes, but also just for people not just to risk their lives and explore, but to just see what it's like to go for a ride.

And lots of people are doing that now.

Well, if you'd asked me the same question about airplanes in 1920, say, after we'd had a big area of government development with the First World War, and then the very first airlines started being formed,

One of the first was KLM in Holland.

And they, I mean, it was crazy.

There were no regulations.

Instrument flying didn't exist yet.

Where do you get fuel?

There's not any big infrastructure of runways.
