So? The face of the tower has 60 columns. The wing span of the plane can hit less than 50 of these, so the plane's kinetic energy is "focussed" at first on, say, 45 columns. Now I will even grant you this: Most of the plane's mass meets windows head-on. I don't have the dimensions handy at this time, but I believe the columns were about 0.3m wide, and windows must have been 0.75m or thereabouts. So let's say that only 30% of the planes kinetic energy was available to cut 45 columns - that's uhm 2/3% of the energy per column. 0.6666% of 4,321,936,710J is 28,812,911.4J.First of all we are talking about two separate events. A missile (possibly) hit
and than the plane hitting. You know all of the plane's kinetic energy isn't focused on one column.
That's 33 times the total kinetic energy of your missile, and 156 times the energy the missile adds by being fired instead of just being on the plane!
Maybe. Since both are comfortably less than 100%, that means the mass of the plane is not stopped - it penetrates.It will lose momentum on initial impact. As I said estimates of this have varied. In this thread alone (by people who support the official story) I have seen 15% momentum loss and 46% momentum loss.
Yep. It's called "margin of error", and when that margin of error is several magnitudes larger than the effect of the missile, that means, to engineers at least, that the missile is totally irrelevant. Adding it does not change these values.Quite a variation.
Depends on what you mean by "penetrate". Drill a small hole through the steel plate that these box columns consist of? Maybe. That would reduce the column's strength by a couple of % maybe. Nothing significant. Fully break and sever the column? No way in hell! Remember YOU doubt that the plane could do it, and remember that the missile has only 3% of the kinetic energy that the plane can put on EVERY column in a worst case scenario?The missile/projectile is focused on a single column, and can probably penetrate it with it's own kinetic energy.
I guess now is the time for you to show calculations what 860,481J of missile energy can do to the WTC perimeter columns around the 80th floor!
The plane has several thousand times the energy that the missile has. It has no trouble at all.Saving the plane the trouble from having to do it.
This is really like my preivious example: It's like putting a small coin on a plank, hoping it will break the plank, saving you the trouble from having to do it with your full weight.
To penetrate how much further? 0.004% further? On a building that's 240ft deep, that's 0.1 inch further.Allowing the plane to penetrate further before other parts of the plane encounter resistance.
Nope. Spot-on.Your penny example is a bad one I believe.
Your example is missing one important thing that mine did include: I took care of the 0.004% difference the missile makes. A 10ct coin has about 0.004% of my mass.I believe it is more like what professional stuntman or wrestlers do. If they are going to be hit by a chair or something wooden, it is always pre-cut. ... Is this a perfect example? Probably not, but I think you get the point.
In your chair example. Let's say the wood that need to get broken is 1 inch thick. Your example would fit if your precut went 0.004% of an inch deep. That would be 1 micron! The thinnest hair on your body is 40 times thicker than that.
Would this precut help your wrestler significantly? If you suggest this approach - precutting 1 micron deep, what would the wrestler do to you, huh?
No sweat. We were in the same ballpark. That error is well within the margins of error we are talking about here. Doesn't matter much if the missile adds 0.004% or 0.003% or 0.005%. All of that is pathetically irrelevant. Even if it added 0.4%, a hundred times more, it would still be irrelevant.You are right about the joules. I used 22kg by mistake. I apologize for that. I must have been going to fast, and had the 1 Kg = 2.2 pounds stuck in my head. So I am sorry for that.
