There are a lot of variables in this. There is a case of an Airbus 330 running of fuel on a flight from Ontario to Portugal it descended in a glide from 34,500 feet over 65 miles in about 19 minutes and landed safely. I believe the "Best Glide Speed" for an Airbus 330 is around 215 knots. But their ground speed could have varied a lot depending on wind, weight and any other damage there may have been. |

I recalled Gauss’s Law from college physics after hearing that lightning might have hit the plane. Gauss’s Law concerns electrical conductivity. It proves that you’re safe from lightning electrocution if you’re in a metal shelled container like a car or a plane. I guess I forgot an important detail. It just means that you as an individual will be safe from the lightning but not the car or the plane. Me, QAANAAQ, you NOT. |

Thanks, Quirt. That was a decent explanation. I'm surprised, I guess, that radar doesn't extent over the oceans. I thought that would have been done for air traffic control, if nothing else. I hope investigators can solve this mystery. |

If you look at a sectional, which is basically a map that shows what ATC governs what airspace, you'll see that it's primarily for regulating air traffic in a very specific region. After leaving the pattern and departing that particular tower's jurisdiction, everything is pretty much done via radio. |

Was just reading a comment that it is possible that the ROHS directive was responsible for the problems on The Airbus. I can't find anything to confirm that the Airbus 330 was one of the first aircraft to comply with the ROHS directive, but if it was, the comment makes sense. ROHS (Restriction of Hazardous Substances) requires the removal of lead from solder used in electronics circuit boards. One of the side effects of this is that tin "whiskers" can grow on the boards, which if they become long enough, can short out parts of the board. This is a fairly well documented problem. RoHS and tin whiskers Since the presence of tin whiskers is rarely obvious to the naked eye, mysterious system behavior, faults, or failures often occur, such as the shut down of Connecticut Millstone Nuclear Power Station in Spring 2005, when its Unit 3 reactor accidentally tripped because of a tin whisker in a control circuit. The problem is even worse in defense systems such as smart munitions, which sit unused for years and decades. RoHS-compliant leadless solder would certainly facilitate tin whiskers, putting military systems and lives at risk all over the world. According to Wiki: Tin whiskers caused the failure of the Galaxy IV satellite in 1998 Here'sa link to a NASA webpage covering the problem: NASA Goddard Tin Whiskers Photo from Wiki showing the whiskers growing: ![]() Airbus appears to be suggesting that the pitot tubes contributed to the problem, but now more evidence is surfacing of problems on other Airbus A330's. Comments are starting to appear about the possibility of tin whiskers contributing to the problems. |

Couldn’t transoceanic flights transmit flight data to a satellite and then to a ground station to be stored? This would provide a duplicate record of data in addition to the plane’s internal flight recorder. |

The very best explanation I've seen on why the plane crashed came from today's tv interview with Sullenberger. He brought the reporter into an Airbus flight simulator and a Boeing flight simulator. He then showed how it would have been impossible for a crew in the Boeing not to know what the other pilot was doing as compared to the ease at which the Airbus cockpit lends itself to pitch confusion. |

One of my orthopedic surgeon friends flies and his brother flies for FedEx. He went to a lecture/talk given by Story Musgrave (Space Shuttle pilot). Musgrave said that the problem with the Airbus design is that, as Jolly said, there's no interaction between the controls of the right and left hand seats. Also, since it's really "fly by wire" there's no tactile feedback telling you that you've pulled up too hard. It'll just keep trying to follow your command. Also, unlike Boeing aircraft, the "yoke" on the Airbus is a stick on the left side of the pilot, like in the armrest of your car. The copilot's is on the right. It's a one-hand thing, and goes against the gut-feeling training that a lot of pilots have. The "sticks" don't talk to each other. |
