Roswell
From Memory Alpha, the free Star Trek reference
Roswell was a city in New Mexico on the North American continent of Earth.
In 1947, Quark, Rom and Nog crashed in Roswell, after arriving from the 24th century though a time warp. The three Ferengi were captured and studied by the U.S. Army but were eventually freed by two helpful humans. They were able to recreate the time warp and return to their own time.
The Army also convinced a reporter in Roswell to retract his initial report of a crashed flying saucer and instead report that it was a weather balloon. (DS9: "Little Green Men")
The weather balloon reference was also used in the real-life Star Trek: The Experience, where by at the end of the Klingon Encounter ride, a television screen in the hallway depicts a military official dismissing reports of spacecraft over Las Vegas as weather balloons.
