15 years 911 twin towers was it a controlled demolition ???

[Deuce]

Yes, but I do not expect a person in denial to accept it.

For whatever reasons, you are not candid enough to have ever mentioned what sort of airplanes you were flying in 2001, to ever have discussed what sort of airplanes you supposedly still fly. No big deal, but just a suggestion of some sort of insecurity in that regard. So pardon my skepticism regarding your desire to have an open and mature discussion of such matters.

You seem to do the same regarding your cell phone experiences, and so I'm skeptical of that.

I know what I did with helicopters and cell phones for several years beginning in 2002, and I don't mind talking about it. I don't mind talking about my knowledge regarding cell phone system design as a result of studying for FCC Amateur Radio license.

You won't even comment on the change from analog to full digital in the cell phone system, so again some sort of insecurity seems to be apparent, or else your version of rational and honest public dialogue is very different than mine. Many posters are very comfortable admitting when they are wrong from time to time, but you're not one of them.

Despite your claims, the cell phone system in 2001 and after was significantly different than it is today, and it is fundamentally dishonest to claim otherwise.

Why did aviation headsets with built-in plugs begin selling in 2001?

In 2001 I was flying Cessnas around New England as a flight instructor. Today I fly a business jet. I've also flown small twin piston charter planes and turboprops.

One step forward, bravo.

I give up Deuce, why did aviation headsets with built-in plugs start selling in 2001, and which headsets are you talking about?

Your quote, HD, but thought I would ask you.

"Why do you keep refusing to admit you might be wrong? Dishonest posting tactics is why, and likely much more. "

Seems to be a perfect fit.eace

At Pilot Communications USA we have been instrumental in bringing
cutting edge technology to the aviation market. In 2001 we introduced
the first aviation headset with a cell phone input. Today we are very
proud to present BluLink, the world’s first wireless cell phone and
music adapter for general aviation!

If in-air communication was impossible above 1500AGL, this is a very strange thing to do.

It's because I'm not wrong Mike. I could predict when I would see NO SERVICE light up my cellphone there in the helicopter--every time I took it above 1500', which was not all that often. I know what happened, and my boss was in on it too, in the other seat. It happened and you don't believe it. And that is your problem sir, not mine.

in your mind, your right. You believe your not wrong.
Strawman conclusion on your part. Did you fly everywhere.

Good to know you know more than specialists back then.

Heck, I don't need to be in an aircraft today to find spots where cellphones don't work. Have done that by car. Therefore it must be impossible to make calls from a car. (using your illogical thinking).

Once again, HD, you use only your frame of reference, while many of us use multiple frame of references before making statements.

I am talking about the physics and design of an operable cell phone system, including limitations of the system, and goals of the system. What the system can and cannot do.

Knowledge, Mike. I had knowledge in those days from studying radio ****, that you still don't have today. I'm really sorry you don't have that frame of reference, but I never expect a thing from the audience.

Others in the radio business do have that frame of reference, and call me crazy and I thought perhaps one was here in these forums, but I was wrong.

Sorry for you HD. Seems you cannot come up with anything to back up your personal claim.

Unless you flew the exact path as the flights on 911, your personal example is meaningless. Like I stated there are dead spots even today in the cell system.

and unlike you, I backed up what I stated about cell calls from aircraft back in 2001 with a source. You seem to be incapable of doing so.

This was a dead issue long before Henry brought it up in this thread. No reason to give it any more attention.

Just like the psychiatrist said...refusal The people in control of this country when this happened got just what they said they would get from American citizens... sad I deal with logic not emotions I will put my cards on the structural engineers not politicians

Physics. What law of physics stopped cell phone signals at 1500 feet? What allowed us to finally get around that pesky law of physics?

If cell phone signals don't work at 1,500 feet above the tower, how do they work at 1,500 feet horizontal from the tower. There must be cell towers on every block.

Directional antenna arrays favouring the topography of each site.

The challenge with cellular networks in densely populated areas is stopping the signals going too far.*

So HD has that and a couple of other little technical issues going for him.

AKA he is NOT 100% wrong.

Maybe 98% :doh




* For most of the land area of AU we have the opposite problem - too few people scattered over distances so "in the outback" the layout goes for longer range transmission with directional arrays focussed along the highways. Not many people off the highways. Lots of kangaroos but most of them I see don't have iPhones.


...yet!

A variety of laws Deuce, many of them designed into the system by the humans who created it. Also the law as demonstrated by Faraday cages. The airplane fuselage is effectively a Faraday cage.

Further, the system was designed and marketed for pedestrians on the surface of the planet. It was NOT designed for people in airplanes, either GA or airliners.

You should familiarize yourself with how they worked in those days. Handing off from cell to cell, faraday cages represented by cars and airplane fuselage, type and characteristics of wave form and wave length, and a variety of other issues that you have no clue about. Presenting yourself as some sort of expert, implied or otherwise, makes you look really bad.

Lets just cut to the chase so we can end yet another rehashing of yet another long-ago falsified claim:

1. Which phone calls from planes on 9/11 were made from cell phones? Identify each one please.
2. Why was each one "impossible"?

Please just for once do not resort to any of your four standard evasions.

Yes Mark, let's cut to the chase. You show the list of which calls were individual cell phone, and which were Airfone. Then show the contract between Airfone and United Airlines, and Airfone and American Airlines with dates covering 9/11/2001

Then we can progress. :mrgreen:
