The City of Roswell invites UFO enthusiasts and skeptics alike to join in the celebration of one of the most debated incidents in history. The three-day event will feature guest speakers, authors, live entertainment, a costume contest, a pet costume contest, parade, family-friendly activities and more.

In early July, 1947, a mysterious object crashed on a ranch 30 miles north of Roswell. The Roswell Army Air Field (RAAF) issued a statement claiming to have recovered a crashed "flying disk." An article ran on the front page of the Roswell Daily Record and the next day, RAAF changed its statement to say that the object was a weather balloon, not a flying disk as they previously reported. This revised statement sparked immediate controversy and has continued to be a topic of debate more than 60 years later.
