I've always wanted to be part of something that would radically change the world. . . . People forget the power of inspiration. All of humanity went to the moon with the Apollo missions. The issue was cost. There was no chance to build a base and create frequent flights. That's the problem I would like to solve.

Engineering is the closest thing to magic that exists in the world.

When Henry Ford made cheap, reliable cars people said, 'Nah, what's wrong with a horse?' That was a huge bet he made, and it worked.

It is despairing to consider that the cost and reliability of access to space have barely changed since the Apollo era over three decades ago. Yet in virtually every other field of technology, we have made great strides in reducing cost and increasing capability.

I realized that a methane-oxygen rocket engine could achieve a specific impulse greater than 380.

Weighing too much on someone's talent and not someone's personality. I think it matters whether someone has a good heart.

For me it was never about money, but solving problems for the future of humanity.
