    Why would the stresses on a horizonatally descending
    meteor be greater than one falling vertically?  The air
    in fact is softer than the ground, so in your theoretical
    situation (and theory it is) your meteor would simply
    slow down and eventually drop to the ground.  Do
    meteors explode when hitting the ground?  They lay
    there as rock!  Your explanation is not what your
    scientists observe in meteor behavior.  Meteors do not
    explode.  They are rock, which may heat to the point
    of being molten but that does not cause an explosion.
    Do your blast furnaces explode when the metal gets
    to the molten stage?  It behaves as a liquid, and a
    meteor heating to the molten stage would behave as
    lava on the move through the air.  A Meteor
    disintegrate into pieces, theoretically, but then some
    remnant would be laying about, but none has been
    found in spite of extensive Tunguska searchs.

    The reports of a horizontal line of fire in the sky, east
    to west, does NOT fit a falling meteor, in fact, as they
    behave as trajectories do, descending to a near vertical
    drop by the time the touch the ground.  The
    atmosphere softens their passage as water does to a
    bullet fired into it.  Do bullets streak endlessly through
    the water, or do they slow and drift to the bottom?
    Have you heard of the Prevailing Westerlies?  The
    wind blows steadily west to east, because of the Earth’s
    rotation.  Methane is lighter than air, and rises.
    Combine these two ingredients and you HAVE your
    near horizontal streak, in a spark lit methane mixture at
    higher altitudes carrying the burn ALONG the path of
    the methane mixture back to the ground.  This fits, and
    your horizonatlly steaking meteor, which then explodes
    to leave no dust or trace of itself, does not.
