Apparently, the parts were quickly scooped up and taken away to be investigated. Theorists believe that the parts were taken to Area 51. Locals and news media were in an uproar about the parts as the government never gave a formal answer as to what it was.
The Kennedy Assassination
US citizens tend to distrust their government, especially when it comes to national catastrophes such as the assassination of a beloved president. On November 22, 1963, John F. Kennedy was killed in a motorcade. Lee Harvey Oswald was arrested for the killing and then murdered on live television.
Of course, people had their suspicions. It was bizarre to see the man who murdered a US president get killed in such a public setting. Some people have said that the Mafia, the CIA, Cuba, or even the Soviet Union hired Oswald to kill JFK and then killed him to keep him quiet.
Bigfoot
Bigfoot has been (allegedly) sighted all over the US. From Alaska to Florida, nearly every state as a documented Bigfoot sighting. For some reason, Washington state seems to have the highest amount of sightings.
