Carl Sagan's Solar Sail Is Ready For Its First Test Flight

Carl Sagan explains why aliens are not visiting us all the time

If all the reports of UFO sightings are real, then Earth must be the most popular destination in the Universe. Obviously, that's a ridiculous anthropocentric notion, as Dr. Carl Sagan explains in the must-see 1966 CBS documentary UFO: Friend, Foe, or Fantasy hosted by Walter Cronkite.
