    The flex is actually no worse than a 777 or 747. The tip is riding higher by about 3 metres in normal flight. What makes it look worse is that the wing tip is almost already at the level of the top of the fuse, so the normal flex takes it above the fuse, which is giving us an uncomfortable illusion. IIRC the “expected” max load will flex it about 8 metres up.

    I presume you have seen pictures of test rigs where they complete all the appropriate load iterations, then take it to 150%, then take it to snap/destruction? I saw the A310 wing with the tip pointing vertically, it snapped that afternoon, which I unfortunately didn’t see or hear.

    As for the Winglets, this wing has been designed with the “New knowledge” of wingtip vortice control in mind, so the devices are less prominent. The beautiful curly winglets from APB are retrofit or added new to a wing that was designed without the “New Knowledge”.

    Of course we new about the tip vortices, the new knowlege I refer to is the desire to do something about them.

    I watched “The Informant” on the flight last night. A true story, starring the (IMO) very very talented Matt Damon.
    A very enjoyable film.

    And I quote: –

    EGPH, at Cornell University they have an incredible piece of scientific equipment known as the tunneling electron microscope. Now, this microscope is so powerful that by firing electrons you can actually see images of the atom, the infinitesimally minute building blocks of our universe. Roger, if I were using that microscope right now… I still wouldn’t be able to locate my interest in your problem.

    Being 3 ROWS behind a person on an aeroplane, for 6.25 hours crossing the pond, and his BO was enough to resolve the conflict in Afghanistan. What the person next to him, and the rows nearby were going through I shudder to think.
    Surely these people have friends that can tell them they stink like a rotting horse dipped in dead worms?

    In the business world, hand shake to both M & F is very normal in my circles. A peck on the cheek to a F is probably crossing the line and I wouldn’t do it. She may bat for the wrong team anyway.

    In the social world, one may get away with a peck on her cheek, but again I wouldn’t do it if it was a first meet.

    If he’s a bro, I wouldn’t do the high-five either.

    I don’t know the exact case you’re referring to (no link – ?)

    I never use links. It’s supposed to be a no-no in forums.

    They’ve been arrested for child trafficking. No surprises there then.
