"It's extraordinary, extraordinary. I hope I can maintain what I feel now. I hope I never recover. I don't want to lose it. It's so much larger than me and life."
William, who was born in 1931, flew aboard a Blue Origin flight, designed by Amazon boss Jeff Bezos.

"What you have given me is the most profound experience I can imagine," he added.
"It hasn't got anything to do with the little green men and the blue orb," William shared.
William was overcome with emotion
"It has to do with the enormity and the quickness and the suddenness of life and death. To see the blue color whip by you, and now you're staring into blackness, that's the thing… You look down, there's the blue down there and the black up there. There is Mother Earth and comfort, and there is, is there death? I don't know, but is that death? Is that the way death is? It was so moving; this experience, it was something unbelievable."
William, who gained fame portraying Captain Kirk on the original Star Trek in the 1950s and 1960s, was joined by co-founder of satellite company Planet Labs, Chris Boshuizen, and software executive Glen de Vries, as well as Audrey Powers, Blue Origin's vice president of mission and flight operations.
When he arrived back on land, William also spoke of the "vulnerability" of the Earth, sharing that he "would love to communicate as much as possible about the jeopardy [of Earth]".

"The moment you see the vulnerability of everything. This air, which is giving us life, is thinner than skin, it's a sliver, it's immeasurably small, it's negligible."
As the capsule arrived in space, soaring past the Kármán Line,William's Twitter account shared a tweet with a quote from Isaac Newton which read: "I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, diverting myself in now & then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."
