The Secret Tape - Calvin Passed Out

Calvin and charley discussed what to tell people right after the incident. They decided to inform everyone that calvin had passed out and could not remember anything on board the u f o. The men must have at least suspected that their conversation was being monitored, either by tape or by someone listening in the hall or in another room. Could they have been lying about the whole thing? I can't rule it out. However, we do have some evidence pointing in the other direThey did pass polygraph examinations, and calvin did so after he admitted to being awake the whole time.
