John Kennedy actually said...

"Yet the vows of this Nation can only be fulfilled if we in this Nation are first, and, therefore, we intend to be first."

"just like when John Kennedy said we'd get to the Moon by the end of the decade, it worked out."

". . . our leadership in science and industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to . . . become the world's leading space-faring nation."

"Any nation that wants to remain No. 1 on Earth must also be No. 1 in space."
