    I just caught the end of a newscast where during takeoff the airliner rolled to the left (around 45 degrees) and the wingtip hit some sort of structure next to the runway.
    No further information.
    Anyone else see this?

    The scary part of this was that the pilot supposedly reported that the roll to the left was not commanded...… At least that's what they said on the evening news... If that's the case that's really troubling...

    Sounds like wake turbulence from a heavy, but pretty extreme for an aircraft that large. If the winds are just right, weird things can happen with wake turbulence.

    Didn't think of that (wake turbulence) but it makes a lot of sense and would depend on the crosswind component... good catch Taz...

    Didn't an A32x crash in NYC shortly after 9/11 from wake turbulence?

    For what it's worth, I had a similar 40+ degree bank plus nose dip about 100' in the air in an MD-80 when an engine crapped out on takeoff. It seems like that would be an obvious issue and mentioned in the article, but who knows.

    Indirectly... pilot error (first officer).
    From Wiki:
    ....attributed the disaster to the first officer's overuse of rudder controls in response to wake turbulence, or jet wash, from a Japan Airlines (JAL) Boeing 747-400 that took off minutes before it. According to the NTSB, the aggressive use of the rudder controls by the co-pilot caused the vertical stabilizer to snap off the plane, along with the plane's two engines separating from intense forces before impact....

    It was an A300-600, which is not fly-by-wire.

    I agree. Besides, pretty much every roll from extraneous weather, winds, wakes, etc are uncommanded.
