Using real science, thistakes a look into the possible theories of how alien craft could operate -- from the propulsion systems, to levitation, to teleportation, and faster-than-light travel.\r

Its secretive nature and undoubted connection to classified aircraft research, together with reports of unusual phenomena, have led Area 51 to become a focus of modern UFO and conspiracy theories. Some of the ivities mentioned in such theories at Area 51 include:\r
\r
The storage, examination, and reverse engineering of crashed alien spacecraft (including material supposedly recovered at Roswell), the study of their occupants (living and dead), and the manufure of aircraft based on alien technology.\r
Meetings or joint undertakings with extraterrestrials.\r
The development of exotic energy weapons for the Strategic Defense Initiative (SDI) or other weapons programs.\r
The development of means of weather control.\r
The development of time travel and teleportation technology.\r
The development of unusual and exotic propulsion systems related to the Aurora Program.\r
Activities related to a supposed shadowy one world government or the Majestic 12 organization.\r

Many of the hypotheses concern underground facilities at Groom or at Papoose Lake (also known as S-4 location), 8.5 miles (13.7 km) south, and include claims of a transcontinental underground railroad system, a disappearing airstrip (nicknamed the Cheshire Airstrip, after Lewis Carrolls Cheshire cat) which briefly appears when water is sprayed onto its camouflaged asphalt, and engineering based on alien technology. Publicly available satellite imagery, however, reveals clearly visible landing strips at Groom Dry Lake, but not at Papoose Lake.
