Step 1 : Introduction to the question "What is the centerpiece of New Mexico’s International UFO Museum?"
...New Mexico’s International UFO Museum and Research Center focuses on exhibits about the Roswell Incident, arguably America’s most famous UFO conspiracy theory. The incident refers to the 1947 crash of an Air Force weather balloon, which spiraled into alien spaceship theories and gave birth to a new “UFO headquarters” of sorts in New Mexico. The museum also has general info about UFO sightings, crop circles, alleged abductions, and an extensive research library.
