Space Trap

They were trying out a new drive when a cosmic accident took them incalculable light years off course. A miracle of courage and astrogation meant than there were some survivors from the inevitable crash. The ship itself did not escape unscathed. What had been their vehicle became their prison. The buckled lock could not be opened from the inside and they had no other means of getting free. The air was slowly running out. The planet they had hit was raw and primitive by their own standards, but it did hold intelligent life. One of the natives found the ship. Dare the trapped space travellers hope for a miracle? If they go out what kind of strange life forms would they be involved with? Could they hope to find the kind of raw materials which would get their crippled ship into space again? If not, could they face life sentences on this strange, unknown, primitive world . . . ? Faced by a thousand fantastic difficulties the astronauts battled untiringly for their right to survive.
