A former senior aerospace engineer at Boeing's Phantom Works research unit,
fired last year under disputed circumstances, is going public with concerns that
the new 787 Dreamliner is unsafe.

Weldon's allegations will be aired tonight byDan Rather, the former CBS News
anchor, on his weekly investigative show on cable channel HDNet.

Weldon alleges:

· The brittleness of the plastic material from which the 787 fuselage is built
would create a more severe impact shock to passengers than an aluminum plane,
which absorbs impact in a crash by crumpling. A crash also could shatter the
plastic fuselage, creating a hole that would allow smoke and toxic fumes to fill
the passenger cabin.

· After such a crash landing, the composite plastic material burning in a
jet-fuel fire would create "highly toxic smoke and tiny inhalable carbon
slivers" that "would likely seriously incapacitate or kill passengers."

· The conductive metal mesh embedded in the 787's fuselage surface to conduct
away lightning is too light and vulnerable to hail damage, and is little better
than a "Band-Aid."

As far as the last item is concerned, there seems to be some definite concern in
this area after a UK helicopter crash resulting from failure of a composite part
struck during a thunderstorm.

But at least clean up will be minimal, becuse so quickly and so little
will be left of that 787. Might only shut down a given airport for an
hour.
