So that makes Popular Mechanics and those particular experts any less credible than say, the 19 year old college student who made Loose Change and Dr. Griffin? The chief editor is related to Michael Chertoff? I happen to think Popular Mechanics has a good reputation and I dont think their intention was to tow the goverment line, but to answer the various conspiracy theories out there.
For example, I have been hearing for years that it a plane did not hit the pentagon, even where there are dozens of witnesses that identified it as an American Airlines plane. They say, first a car bomb, then it was a Global hawk, then it was a cruise missile because the hole was too small, then it was a remote controlled plane, then the witnesses that saw the AA Boeing were 'in on it', etc..Well, what happened to the passengers? Now, they apprently moved the goal posts with this one, but still can't admit that Islamic terorrists did, anythig BUT Islamic terrorists. The only way I have heard conspiracy theorists say it was Bin Laden and al queda was in that they were all CIA operatives and yes I know about Afghanistan in the 80's.
I'm in the camp that it was done by Islamic terrorists and the intel services 'allowed it to happen' with their incompetence. There have been huge intelligence failures that date back to the mid-90's. This does not mean it was a huge government conspiracy, it was government negligence. Does this mean Im a Bush operative Neo-Con who believes the 'official story'? No it doesnt, I made up my mind by doing plenty of research, including the conspiracy theories. The 9/11 commision was a CYA commission. I would recommend people check out the following site and books:

I do see things that are unanswered, but just can't jump to the conclusion that it was a huge Neo Con conspiracy and just because unrelated documents exist such as Operation Northwinds, doesnt mean that the CIA performed 9/11. If the PNAC was so evil and sinister, and they hatched the attack, then why has it been on the internet for the public to see for something like 5 years before 9/11 even happened? Hasnt Bin Laden openly admitted to 9/11 numerous times as well as videos of the Atta in Afghanistan pop-up?
If there are unanswered questions, fine. But some of those conspiracy theories just ignore reality and fact and replace it with a conspiracy that really cannot be proven. They make these huge jumps to conclusion which sometimes defies logic. That where it really comes down to. People will believe what they want.
