3/21    After a plane crashes badly and turns into a big pile of charred
        rubble, how is it possible for the investigators to determine whether
        it is mechanical failure or human error?  (Let's say they have already
        ruled out bombs.)
        \_ failure analysis.
        \_ black boxes.
        \_ black boxes, eye witnesses, air traffic control, larger chunks
           of debris which may have been left behind...
        \_ Many small parts survive the most destructive crashed. Example,
           depending on the state of the filament of a indicator light
           from the cockpit, crash investigators can tell if the light was
           on or off at the time of impact. Same thing for engine parts
           and propellers. they can tell if things were rotating or stopped
           at impact based on the shape of deformation. it is a science.
           \_ Wow.  I see.  Thanks.

2/10    About the Lexus that crashed because of (supposedly) a stuck
        accelerator padel, why didn't the driver simply put the transmission
        in Neutral?  If the cop passenger had time to press at least one
        button to dial 911, wait for the call to be picked up, and had a
        10-second-plus conversation with the operator (which was played back
        in media reports), wasn't there much more than enough time to tell the

        \_ Not every kind of failure can be measured by maintenance cost.
           Complete engine failure is more costly than brake-line leakage, but
           is less likely to kill you.

3/26    I've never been to Hawaii before, but I just booked a flight to
        Kauai for me and my gf (who has been to Oahu). I'd like some
        travel advice. Which side of the island to stay on, what not to
        miss, etc.
        \_ There's not a huge amount of choice as to "where to stay",
           it's a small island.  Shell out the $$$$ for a helicopter

        \_ Just curious, what's wrong with your transmission?
