Jet's flaming space junk scare

Pieces of space junk from a Russian satellite coming out of orbit narrowly missed hitting a jetliner over the Pacific Ocean overnight.
The pilot of a Lan Chile Airbus A340, which was travelling between Santiago, Chile, and Auckland, New Zealand, notified air traffic controllers at Auckland Oceanic Centre after seeing flaming space junk hurtling across the sky just five nautical miles in front of and behind his plane about 10pm.
According to a plane spotter, who was tuning into a high frequency radio broadcast at the time, the pilot "reported that the rumbling noise from the space debris could be heard over the noise of the aircraft.
"He described he saw a piece of debris lighting up as it re-entered [the earth's atmosphere].
"He was one very worried pilot, as you would imagine.
"Auckland is talking to [an] Aerolineas Argentinas [pilot] who is travelling [in the] opposite direction at 10 degrees further south asking if they wish to turn back to Auckland.
"They have elected to carry on at the moment.
"[It's] not something you come across everyday and I am sure the Lan Chile crew will have a tale to tell."
The assistant secretary of the Australian and International Pilots Association, Captain Steven Anderson, who flies for Qantas, said that based on the details of the report, the debris could have caused catastrophic consequences had it actually struck the aircraft.
"For [the pilot] to have heard it, one of two things - [the debris] was a lot closer than he thinks or it was bigger and going at quite a high speed.
"In other words, it's caused the piece to break the speed of sound which is what he's heard - the sound barrier.''
A spokesman for Airways New Zealand, which provides air navigation services across airspace known as the Auckland Flight Information Region, confirmed the incident to smh.com.au this morning.
He said it occurred about 10 minutes after the Lan Chile flight had entered the Auckland Flight Information Region.
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].
Airways New Zealand then provided that information to airlines and pilots that would be travelling in that region at that time.
They could then decide for themselves whether they wished to fly during that period.
"But clearly there has been a timing issue," the spokesman said.
"Either the time that was indicated to us was incorrect or the satellite de-orbited early."
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.
A formal report about the incident has been logged and recordings of conversations between the pilot and air traffic controllers were expected to be handed over to investigators in the next few days, he said.
The Lan Chile flight landed safely at Auckland Airport at 3.55am today, he said.

Who'd be a pilot? As if seagulls, migrating geese and wind shear wasn't already enough to worry about.

What are the chances, whether on the ground or in the air, of being clobbered by a piece of 'de-orbiting' (I love that word) satellite? Probably less than interception by a bit of rock pushed by gravity-rain into ones path of progress.

My brother is a captain for Qantas and has seen many meteor trails. One though was a large fireball that reflected off the Earths atmosphere coming straight at them. He knew it was 100K+ above him and told his crew don't bother to duck!
I think that the same thing applies here. It is imposssible to get any real idea how close the space junk was.

You all have a bigger problem with cars and trucks coming at you head on every day and they miss by three or four feet (one meter).

It was a meteorite, not a satellite, says Russia http://www.smh.com.au/news/world/rus...761621087.html

It can land in my front paddock anytime.
So long as it misses the kids and the animals.
But as with most things like this, it usually happens to those who aren't interested in it.
