According to NASA officials, the Russian space objectwhich supposedly made the near-miss collision with the Chilean airplane about four hours southwest of Aucklandactually re-entered the Earths atmosphere on schedule and well outside the time as reported by the Chilean pilot.
However, the crew of the Chilean airplane, who was flying over the Pacific Ocean from Santiago, Chile, to Auckland, New Zealand, did have a near miss with something that was described as sounding like a loud roaring noise and visually as several fireballs with falling debris passing within about 9 kilometres  of the plane.

The sensational tale of the falling Russian satellite and the Chilean airliner lasted only a few hours before it was debunked but the erroneous connection of the roaring fireball with a Russian space shot was entirely reasonable, given Chiles long and unusual history of being on the receiving end of Russian space spectaculars.

Experts now doubt that the fiery fragments that narrowly missed an Auckland-bound aircraft were the remains of a Russian satellite.
The fragments thundered past the Lan Chile Airbus 340, which was carrying up to 300 people from Santiago, Chile, about 10pm on Tuesday.
The pilot reportedly saw the objects and heard a boom as they entered the atmosphere, about 10km in front of and behind the aircraft.
Captain Steven Anderson, assistant secretary of the Australian and International Pilots Association, said the objects must have been very large to be heard.

A Chilean jetliner approaching New Zealand came within 20 seconds of being hit by blazing objects hurtling down to Earth, New Zealand aviation officials say.
US space officials said today it was most likely a close encounter with a disintegrating meteor, denying assertions from New Zealand officials that the LAN Chile plane narrowly missed being blasted by Russian space debris that was returning to Earth ahead of schedule.

NASA has discounted claims Russian space junk was responsible for a near-miss over the Pacific.
The pilot of a Chilean jet bound for Auckland reported seeing fiery debris falling near his plane on Tuesday night.
There is speculation it was an unmanned Russian cargo craft returning to Earth after resupplying the International Space Station.
However NASA's chief scientist for orbital debris Nicholas Johnson has checked the records of the 15,000 space objects NASA tracks on a regular basis. He says none fell to Earth during the period reported by the airliner and the Russian rocket re-entered the atmosphere 13 hours later.
Mr Johnson says the pilot probably saw a meteorite burning up as it entered the atmosphere.

An orbital debris expert at Nasa told Associated Press news agency that he had checked with the Russians and that their vessel - a spacecraft resupplying the International Space Station - had fired its re-entry rockets 12 hours after the Chileans reported the near miss.

The Progress M-58 spacecraft (Progress 23) undocked from the Zvezda module of the ISS shortly after 18:00 GMT (2 pm EDT ) 27th March, 2007.
At approximately 23:20 GMT (7:20 pm EDT) the  spacecraft fired its thrusters for a deorbiting manoeuvre and re-entered over the South Pacific Ocean . The spacecraft was filled with ISS rubbish before it was undocked.
 With the Progress spacecraft now gone, the ISS crew will board the remaining Soyuz TMA-9 spacecraft on Thursday to move it from its current docking location on the Zarya module to the Zvezda module. This will free up the Zarya docking port for the next Soyuz mission, scheduled to arrive at the ISS early next month.

Because the timing was wrong, the coordinates of where the satellite was supposed to enter the Earth's atmosphere also turned out to be incorrect.

Airways New Zealand had been warned by Russian authorities almost two weeks ago that a satellite would be entering the earth's atmosphere sometime today between 10.30am and midday NZ time (6.30-8am WA time).
Airways New Zealand then provided that information to airlines and pilots that would be travelling in that region at that time.
