Gold in the Sky by Alan Nourse

YOU WILL MEET– Greg Hunter. Test pilot–happy only when his life hung in the balance. Tom Hunter. A pioneer–his frontier was hidden in test tubes. Johnny Coombs. A prospector–he returned from the asteroids too soon. Merrill Tawney. An industrialist–he sought plunder even beyond the stars. Major Briarton. A government man–his creed was law and order.
