I called to the other men that the sky was clearing, and then a moment later I realized that what I had seen was not a rift in the clouds but the white crest of an enormous wave.

If I had not some strength of will I would make a first class drunkard.

Later, I realized that the mission had to end in a let-down because the real barrier wasn't in the sky but in our knowledge and experience of supersonic flight.

Clear sky is bigger than the largest rain clouds.

The color has faded out of the sky. It is grey, becoming darker as the world turns herself round a little more. The clouds are long and black and ragged, like the wings of stormbattered dragons.

Difficulties are just things to overcome, after all.
