Way back, I believe the first jet passenger jet was the Lockheed
Electra. The plane mysteriously fell out of the air and very thorough search for a cause was instituted. In the end, again if I remember correctly, the conclusion was that the wing spar failed from fatigue because the wing was nutating, a slight circular motion due to gyroscopic effects. Maybe that's the same thing caused the FL seaplane crash. |

To jog your memory: http://en.wikipedia.org/wiki/Lockheed_L-188_Electra Maybe that's the same thing caused the FL seaplane crash. The Electra problem happened pretty soon after they came out. Those seaplanes have been around a long time. Cheers, Kev |

Maybe that's the same thing caused the FL seaplane crash. The Electra wasn't a jet, it was a turbopropeller. Furthermore, the Electra's design flaw was discovered early in it's life cycle. Grumman Mallards are a mature design of 70 years starting with the Goose. D. |

Maybe that's the same thing caused the FL seaplane crash. Except the Electra wasn't a jet. Maybe you are thinking of the Comet. The Electra did, however, have a string of catastrophic early failures, which were eventually traced to metal fatigue in the wing or fuselage structure caused by a vibration or oscillation that occurred in flight and was associated with the design of the plane; and the Comet had a series of catastrophic early failures which were eventually traced to metal fatigue and crack grown around the windows occurring after multiple pressurization and depressurization cycles. Both were prime examples of the learning process associated with civil aviation and aviation technology. Am I recalling this correctly? |

Are you thinking the English Comet? It had several inflight mysterious
breakups before it was discovered that the square windows created stress fractures after several pressurization cycles. I believe it was the first pax airline. |
