Introduction Of Heiwa, Planes should not collide with towers Options

[Heiwa]

Hi all. I am Heiwa. Naval architect. Designing ships since 40 years. Quite complex! Lots of forces acting on a ship structure in the interface water/air affecting strength, buoyancy and stability. Like planes. Structures fixed on land are easier to design. Take a tower/skyscraper:

A tower/skyscraper structure consists generally of load carrying elements of only two types, i.e. vertical steel columns and horizontal composite steel/concrete floor panels, all joined together one way or another, e.g. by bolts.

The vertical elements, the columns, joined on top of each other are primary structural elements that transmit their loads down to ground.

The horizontal elements, the floor panels, placed between and connected to the columns are secondary structural elements that transmit their loads to the columns.

And that’s it. Nothing magic at all! Not like a ship or a plane.

If a skyscraper has 110 floors, like WTC, there are thus 110 assemblies of horizontal floor panels all connected to the vertical columns. Evidently the columns between ground and the first floor are designed to carry 110 floors and the columns below the top floor (or roof) are designed to carry just one floor (or the roof).

It means that the lowermost columns of a tower structure are 110 times stronger than the topmost columns.

Airplane pilots are highly recommended not to fly their planes into towers/skyscrapers, as the vertical and horizontal elements of the towers/skyscrapers will slice/shred the plane into small pieces. Evidently the plane will cause some local damage to the structural elements of the tower or skyscraper … but that’'s it.

Anyone believing that flying planes into the weak tops of skyscrapers will destroy or crush the strong bottom parts of same towers should read my scientific paper at http://heiwaco.tripod.com/tower.htm . I am happy to inform that you can in fact fly as many planes you like into the tops of skyscrapers and nothing will happen to skyscraper below impact. The plane's pilot will evidently get smashed.

If you belong to a terrorist organization and plan a flying attack anywhere you should thus avoid flying planes sideways into the weak tops of skyscrapers as you will only produce local failures up in the weak top and kill yourself. Better is to hit the bottoms or Stuka style vertically through the roof. But you will still kill yourself.

I have informed the FBI and CIA about the above and they, Pearl Harbour style, informed that couldn’t care less, I was sorry to hear. They apparently have great difficulties in Afghanistan forgetting the home front. Well, do not blame me.

Consider the possibility (or probability) that as the towers were mechanically destroyed it released heat... When you file metal or sand wood, you mechanically *destroy* the wood or metal.. to dust and shavings...and heat is a by product. If there was mechanical pulverization of hundreds of thousands of tons of material... such as concrete slabs... sheet rock and so forth.. enormous amount of heat would be a by product. You can't not have heat produced from mechanical destruction.

The heat can and will radiate to surrounding materials.. the air and so forth.... but in the case of a gravity driven collapse much of the disintegrated, shattered, fractured and pulverized material seeks it's lowest level... like water would. It's conceivable and likely that the hot material was insulted by the debris above... and there may have been anaerobic exothermic reactions under the pile... which would only add to the heat.

The heat would eventually disappear as it is conducted to cooler surrounding material. The WTC pile remained hot for months... hotter lower down in the pile where there the hot material was insulated. Millions of gallons of water was applied to cool the pile which had chemical added which were supposed to suppress fires if I recall correctly.

Of course another explanation is that some super hot material like thermite was use to destroy the towers and the unreacted material simply made its way to the bottom.. again like water seeking its level and continued to anerobically combust the steel and iron there. This is possible... but I have not seen evidence of this.
