Radiation risk
Recent studies show that passengers and crew members flying on transpolar routes are exposed to unusually high levels of cosmic and solar radiation. According to Robert Barish, a New York health physicist who recently spoke to the International Herald Tribune, the dosage received during each flight along the transpolar route is equivalent to three chest X-rays and may be significantly increased by solar flare radiation.

Cancer fears limit Hong Kong air crews' New York trips
HONG KONG (AFP) — Airline Cathay Pacific has limited air crews' flights on the non-stop Hong Kong-New York route after it was found the journey could increase the likelihood of cancer, a report said Sunday.
Staff of the British-owned, Hong Kong-based airline say they have been limited to just two of the ultra long-haul flights per month since it was found the route exposed passengers and crew to high levels of cosmic radiation when they flew over the North Pole.
Union chiefs told the South China Morning Post radiation levels increase markedly at 26,250 feet above the pole and prolonged exposure could be harmful to cell DNA possibly causing cancers.
"If you do two and a half polar flights a month you are in the danger zone," Flight Attendants Union general secretary Becky Kwan was quoted as saying. |

They do fly over the North Pole, basically most trans polar flights use these routes e.g.(Beijing/New York) those routes have been used for quite sometime but because there are some guidelines and requirements, not all carriers use them.
The U.S. Federal Aviation Administration (FAA) requires U.S. operators to obtain specific approval to conduct polar operations. The approval process validates airlines' preparedness to conduct such operations. The FAA defines the North Polar area of operations as the area lying north of 78 deg north latitude. The FAA information memorandum Guidance for Polar Operations (March 5, 2001) outlines 10 issues:
Airport requirements for designation as en route alternates.
Airline recovery plan for passengers at diversion alternates.
Fuel freeze strategy and monitoring requirements.
Communication capability.
Minimum equipment list considerations.
Airline training.
Long-range crew requirements.
Dispatch and crew considerations during solar flare.
Special equipment.
Validation requirements for area approval. |

i took a flight from ewr new york to singapore. it went north pole (probably not exactly the pole), then came down through siberia, mongolia, china to singapore.
i can't find any pair of big cities in the northern hemisphere that have the exact same longitude and are exactly opposite in latitutude. |

Because santa's workshop has a no-fly zone........it might interfere with the new reindeer practicing their flying lessons. |

there is a no fly agreement over the north pole. |

Often, the auto-pilot and other instruments in a plane depend on using a magnetic compass to tell where north is. Flying over the north pole would cause instrumentation to fail, since when you're at the north pole a compass will just spin around. It's far easier and safer to just go around it. |

Nothing to do with the North Pole weather - you're normally flying higher than a level where it matters - it's a question of distance - the flight path would be longer |

Flight paths hav,nt been built yet. |

There are 2 main reasons.
First, the weather in the very far north is very unpredictable and severe. The rides would be so rough that no one would want to fly over the poles.
Second, the temperatures are extremely cold. The wings and fuselage (body) could possibly begin to ice.
Some military aircraft are built to withstand the extreme wether and cold. None of the commercial aircraft that I know of are built for those conditions. |

Look on a globe, the shortest point between 2 places is not the route we are used to on a flat map, unless you are flying virtually direct North/South!
Planes fly great circle routes. The cities they fly between do not have their shortest routes over the N. Pole. |

The cold drains the fuel faster. |

Is that snow down the there?
No, its reindeer!! |

There's a no-fly zone over the North Pole due to Santa's Village. |

because the earth spins on its axis at around 1,000 miles an hour, if you fly right over and then you will probably miss your destination because you are moving to slowly in a different direction from the earth, and the earth is moving so fast you are so disproportionate that you actually lose more fuel tryin to fly to yur destination again, that is why when you fly west it seems longer because you are moving in earth's direction and if you move east you are bound to meet your destination. |

unpredictable climate perhaps..
or since its too cold, the engine might freeze up ;) |
