The Quatermass Xperiment

The British Rocket Group launches its first manned rocket into space. Shortly thereafter, all contact is lost with the rocket and its three person crew: Carroon, Reichenheim, and Green. The rocket's hatch is finally opened, and the space-suited CarroON stumbles out; inside, there is no sign of the other two crew members. The crew are seen for a time pleasantly at their duties; then suddenly, something seems to jar the ship. Something living in outer space has entered the ship, dissolved Reichheim and Green in their sealed spacesuits.
