Escape into space

The ship rose on a column of invisible, super-heated steam ejected at incredible velocity. The spread of the blast flattened everything in the immediate vicinity. The surrounding town was wiped out. Immediately on blast off the automatic pilot engaged hi-drive to avoid the attacking missile. This put the ship into negative mass with relation to the normal universe. It was now in M-space. The ship was self-contained. It could keep going till all her occupants died of old age. But where to? Proxima Centauri? Or maybe Alpha Centauri, Riga, perhaps, or Sirius! The universe is a big space. They hurtled on through space and time until they saw the planet, a cloud-hidden ball, as it hung in space a hundred thousand miles below the orbiting vessel. It had seas and clouds, mountains and ice-caps, islands and continents, It had a moon and a yellow G-type sun. Home? Was this their second chance?
