Dear MuhammedColumbo,

Ya know, I gotta show you a measure of respect on account of your own personal efforts at 'analysis' with respect to the Pentagon's 9-11 scene. So, since you are a very smart and bright sort of person, I want to share some thoughts of mine own with respect to your personal analysis of the Pentagon's 9-11 photo(s).

I've worked on jet engines and aircraft since 1975. Removed, installed, troubleshot, repaired, built, tested so many jet engines that I no longer even what to service OIL TANKS on jet engines. I'm a "burned out" A&P.

I've had the nasty experience of having a jet engine on its maintenance stand roll over my foot - and THANK GOD the trailer had pnuematic tires or I'd be minus a foot for the rest of my life. And I've been nearly crushed to death during an engine change on account of the wire cabling snapping on the removal/installation gear.

I tell you these couple "war stories" in order to make you appreciate jet engines have significant WEIGHT on account of their having significant MASS. They are truly "substantial" things and are NOT 'weightless/mass-less' images simply seen by the human eye on photographs or in videos.

In physics, there is this very simple equation that is rendered F=m x a, or if you prefer words "FORCE = mass times acceleration"

The MORE mass you have being accelerated, or the MORE ACCELERATION you induce in any mass results in a MULTIPLICATION OF FORCE.

Now a typical jet engine on virtually any commerical airliner WEIGHS IN at well over a TON - and most are now coming in at weights of TWO TONS and greater on account of their increased size and thrust ratings.

I'm not about to quote you what a CFM56 weighs - I really don't care - but its somewheres in the ballpark of 4,000 lbs or two tons.

Take 2 tons of metal and have it moving along at 500 miles per hour (which translates into a certain 'Feet per second' - and you can calculate the total amount of FORCE this engine can induce IF it strikes a stationary object.

If you were to take a 10 pound sledge hammer and swing it a certain amount of 'feet per second', you've have a certain amount of FORCE which could be imparted into/onto some stationary object.

If you took that amount of FORCE from the swinging of your 10 pound sledge hammer and DIVIDED IT INTO the total amount of FORCE contained in a 2 ton piece of metal travelling at 500 miles per hour, you'd come up with an APPROXIMATE NUMBER OF SWINGS OF YOUR SLEDGEHAMMER that would eventually equal the amount of FORCE imparted by your 2 ton jet engine going 500 mph hitting a stationary object.

Now in your photograph, you show the red outline of a Boeing aircraft imposed onto the wall of the Pentagon.

I want for you to LOOK AT the position of the RIGHT ENGINE's red silouhette and LOOK at what is contained in that engine's "Target".

There is this CONCRETE PILLAR.

If I could find about one hundred able bodied men who have the physical conditioning as the result of being CONSTRUCTION WORKERS - and let's say that it would take these 100 men swinging a 10 pound sledgehammer 100 times EACH to approximate the amount of TOTAL FORCE 2 tons of Jet Engine SledgeHammer Metal travelling at 500 mph - and I get these 100 construction workers to take 100 swings with a 10 pound sledge hammer into that SINGLE PILLAR you see pictured within the red silouhette of that airplane's right jet engine - do you think that you are going to see THAT pillar looking as good as it does???

I've seen TWO able bodied/physically conditioned construction workers make MINCE MEAT out of sidewalks and other sorts of masonry work using far fewer strokes of a hand held slegehammer.
