David Adair is an American who says that in 1971, as a 17-year-old rocket builder, he was taken to the secret Groom Lake base known as Area 51 and shown an engine he believed was of alien origin. He has told the story on radio and in many interviews since the 1990s.[1][2]
His account

On Art Bell's radio show on 17 November 1997, Adair said he had grown up in rural Ohio, building rockets from childhood with materials from local machine shops. At 17, he said, he obtained support from Congressman John Ashbrook for a half-ton rocket with an electromagnetic fusion engine, with oversight from retired Gen. Curtis LeMay. He said the rocket was launched at White Sands, New Mexico, accelerated so fast that witnesses thought it had exploded, and was tracked to Groom Lake, where he was flown afterwards.[1][4]
At the base, he said, he was taken into a hangar whose floor descended to an underground bay, met former Nazi rocket engineer Arthur Rudolph and was shown a large engine with no conventional wiring, only a network of fluid-filled tubes, which he concluded was not made on Earth. In other tellings he has said he sabotaged his own rocket so it could not be used to deliver nuclear weapons, that LeMay helped him return home, and that he was later recruited by the Navy. He has also said he received an Air Force engineering award.[1][4]
Public appearances

Adair has said he tried to testify before Congress about his experience. According to the testimony, he also gave an account to Steven Greer's Disclosure Project, which presented about 20 of its witnesses at a press conference at the National Press Club on 9 May 2001.[2][3][4]
Assessment

There is no independent corroboration of Adair's visit to Area 51 or of what he says he saw, and details vary between tellings — for example on how he reached the base. LeMay died in 1990, and no documents confirming his role have been published. Adair's story remains a personal account.[1][4][5]
