Una legge degli Stati Uniti approvata il 16 luglio 1969 che ha reso illegale per il pubblico a venire a contatto con gli extraterrestri o loro veicoli - titolo 14, sezione 1211 del codice dei regolamenti federali. Chiunque trovato colpevole di tale contatto vuoi far fronte alla reclusione di un anno e una multa di $5.000. Also, any individual who had been "exposed" could be quarantined under armed guard by the NASA administrator without a hearing. As of 1991 the law has mysteriously vanished from the U.S. Code of Federal Regulations, with only the cryptic legend "Reserved" to be found where 14 CFR Part 1211 used to be. NASA public affairs specialist Elsie Weigel, stated that NASA removed the regulation in April 1991 "because we never found any aliens." So, officially the Extraterrestrial Exposure Law "has served its purpose and is no longer in keeping with our policy." NASA has "reserved" Section 1211, perhaps so that similar regulations can be reinstated if the agency ever sends humans to another celestial body, or brings back samples via an unmanned probe.
