i'm not trying to send a flame here, but working in the wireless
telecommunications industry, and being a commercial pilot, let's be

this is certainly an interesting slant, but i haven't seen anything
to substantiate this from more conventional sources. remember there
is always butt-loads (aviator's technical term refering to quantity)
of speculation early on in any (especially) aviation accident.

it is always more prudent to wait and see AT LEAST what the CVR/FDR
transcripts show. (a big advantage in a 3 year old air frame) i really
think we will see something a little less controversial...probably
a little more conventional. here is my SPECULATION:

A most unfortunate pilot error, ie. accidental control accuation
during taxi/takeoff phase.

Improper or lack or proper maintenance, inspections, etc. (often found
in central/south american airlines, sometimes so serious that the
carrier is not allowed to fly into US airspace.)

electrical systems flaw/malfunction (causing non-human initiation of
the spoilers/ or thrust reverser bucket


it IS sometimes entertaining to speculate as to the cause, but not
every aviation accident is due to conspiracy or a twilight zone
