So we see a blue sky. We grow up and live in a blue sky, right? The spaceship — and I like to call it that — punched through that at 2,500 miles per hour, 50 miles, 2,500 miles an hour so within the count of two or three it goes from blue, bang, and suddenly it’s black,” Shatner told CBS Mornings last week. “And you see this black, and that’s space and eternity and the mystery of the cosmos. But it’s black, and it’s death and just down there is the blue — you’re on top of the blue looking down on Earth.”
