Was the death of Dr. Robert S. Harrington a cover up?
Dr. Robert S. Harrington, was the chief astronomer of the U.S. Naval Observatory, unfortunately he mysteriously died before he could publicize the fact that Planet X actually is approaching our Solar System for real.
Is esophageal cancer a way to say that he talked to much?
By analyzing time-lapse photographs using the “blink comparison” technique, originated by famed Pluto discoverer, Clyde Tombaugh, Dr. Harrington proved that Planet X was indeed inbound into our Solar System. Harrington sent back reports of this ominous discovery, but died of what was reported to be esophageal cancer before he could pack up his telescope and come home to hold what would have been a highly publicized press conference. The source below indicates that Harrington began the search at Black Birch in April, 1991, two years before his death. However, considering the painstaking process of trying to find a distant needle in a very large haystack, two years is not much time at all.
