Most astronauts have refused to grant him interviews. The most infamous incident involved Apollo 11 crew member Buzz Aldrin, the second man to walk on the Moon. According to Aldrin, he was lured to a Beverly Hills, California, hotel on September 9, 2002, under the pretext of an interview on space for a Japanese children's television show. When he arrived, Sibrel was there demanding that he swear an oath on a Bible that he had walked on the Moon. When Aldrin refused, Sibrel called him "a coward, and a liar, and a thief."[1][2] Aldrin punched Sibrel in the jaw, which was recorded.[3] Sibrel later attempted to use the tape to convince police and prosecutors that he was the victim of an assault. However, it was decided that Aldrin had been provoked, and, based on Sibrel's unfazed, nearly instant reaction to his cameraman, did not actually injure Sibrel, so no charges were filed. Many talk shows aired the clip, often siding with Aldrin's response.[4] Sibrel said later that he wrote a letter of apology to Aldrin.
