Space for Sale - Darrell Bain - Bog

The zany, politically incorrect Williard Brothers are back and this time they're shooting for Mars, trying to spend the billions of dollars inherited from the old Mafia Godfather. But there's a financially and politically powerful organization that's been seriously hampering manned spaceflight by generations, backed by shadowy beings who may not have originated on Earth at all. So far they've kept manned space flight from progressing very far or very fast, but they've never encountered the Williard Brothers, either. Along with their straight shooting girl friends, The Williards intend to go to Mars, and they don't care who they have to kill to make it!
