"Atomic dischargers blow up the saucer from outer space."
Sam is pretty aggressive. No contact just blow them up.
I like the Roswell reference from yesterdays post too. How Sam used technology from the crashed saucers found here on Earth to track these down.
Sam doesn't use computers either he uses "Calculating machines" to predict the saucers path.
We can't think of a world with out computers and they hadn't the foggiest idea what they were.
Things do change in a hurry.
