We Met the Space People

This is a UFO contactee account by two sisters from the Midwest US in the late 1950s. The Mitchell sisters, Helen and Betty, are approached by space aliens, who can pass for human beings, in (of all places) a coffee shop in St. Louis, Missouri. On a second encounter (again in the coffee shop) they are given a schematic for a communicator, which they build, and through it they receive messages from the Space People from Mars and Venus. Unlike the more aggressive aliens of later decades, they wait until the third date to take Helen on a ride to the mothership. There she learns that the aliens have one-piece uniforms that 'feel like satin,' speak a Universal Language, and play a game like shuffleboard when off-duty.
