Astronaut Leroy Chiao, spotted UFOs during a spacewalk outside the International Space Station in 2005. Chiao thus joins the long list of astronauts and cosmonauts who spoke about his experiences with unidentified flying objects out there.
From October 2004 to April 2005, Leroy Chiao was assigned to a mission to the Space Station. To report promptly left the astronaut took a walk outside the ISS with his Russian counterpart Salizhan Sharipov with the aim of installing antennas navigation of 230 miles above the Earth at a speed of 17.000 mph. At that time Chiao, saw lights moving faster than them: “I saw some lights that seemed to be in a line and it was almost like an upside-down check mark, and I saw them fly by and thought it was awfully strange. It wasn’t just one, but a line of them strung out along the South American coast”
The prosaic explanation from NASA is that really what you saw outside the ISS astronaut were lights of a fishing vessel located hundreds of miles below him.
