America's enemies will now know how to bring our bridges down.
Abundant world press coverage of this latest Mississippi bridge disaster has finally alerted the terrorists to the vulnerability of America's bridges.
Everyone knows that if you keep bending a coat hanger that it will finally break.
This is called metal fatigue.
America has 27 thousand more of these structurally deficient bridges that were designed and built before engineers realized how important metal fatigue was in bridge design.
Now they know and modern bridges are built to withstand this. Older bridges were not designed with extensive metal fatigue in mind.
But Americans are still "asleep at the switch" as to what could happen as terrorists listen to this latest Minneapolis bridge disaster.
All the terrorists have to do now is to paint various of these large, old, structurally deficient truss bridges with a chemical that has been available for over a decade, which will cause even faster extensive metal fatigue in many more of America's bridges.
This particular chemical is referred to, on the top of page 132, in Alvin and Heidi Toffler's 1993 book "War and Anti War".
In their book they say:
"Then there is 'liquid metal embrittlement'. It is possible to wage a kind of 'graffiti' war by using a felt marker or a spray can to apply a colorless chemical to key components of metal structures like bridge pylons, airport facilities, elevators or weapons. The fluid causes them to become brittle, breakable and hence unusable."
I honestly believe that certain Russians will be glad to profit from the sale of this chemical to America's terrorist enemies.
This is being posted to ensure that Americans will learn all about this because I'm sure the terrorists know all about it already.
I have written a book "Universities Asleep at the Switch" warning Americans what they are in for if they allow our universities to continue going down the same route as our bridge inspectors.
