Like the questions surrounding JFK’s assassination, I don’t think we will ever have definitive answers to what happened on September 11, 2001. Scientists, some who have since been released from their university or laboratory jobs, have released a paper "Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe" which will likely have conspiracy theorists once again presenting their arguments that the plane alone could not have destroyed the World Trade Center.
We have discovered distinctive red/gray chips in all the samples we have studied of the dust produced by the destruction of the World Trade Center. Examination of four of these samples, collected from separate sites, is reported in this paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan resident about ten minutes after the collapse of the second WTC Tower, two the next day, and a fourth about a week later. … The red portion of these chips is found to be an unreacted thermitic material and highly energetic.

Today on Reddit, the question was posed "2,740 Americans died in 9/11, justifying the removal/restrictions of many of our freedoms. How many people died to give us those rights in the first place?" Within the answers, this illuminating comment:
It’s sort of a nationalistic cliche to say that soldiers fight for our freedom but what they really fight for is the sovereignty of our government, which happens to guarantee us certain freedoms.
When we say a soldier died fighting for our freedoms, what we really mean is that he died in a war which threatened the loss of some or all of American sovereignty to a foreign or domestic power which would likely guarantee less rights than the present government.
This distinction is important because in the history of American wars, very few have definitively fallen under that category – and even in those cases, preserving the rights of American citizens was ancillary to sustaining or expanding the sovereign power of the U.S. government.

We now live with a generation that has never known the feeling, the freedoms, we had prior to September 11, 2001. There is a different feeling. I felt more secure! I wish my youngest children could know that feeling and could experience true trust. I have lived with a tension since 9/11 that I had not known prior. The tension is not from a fear of terrorists; they’ve always been around (well, at least from the 1960s First U.S. Aircraft Hijacked, May 1, 1961 and at least 1800BC for the rest of the world). The fear is from my own government! Prior to 9/11 the police were different; now everyone should fear the police.
Question: “The police are here. They want to talk to me. What should I do?”
Answer: “Make no statement to the police under any circumstances.”

The terrorists won.
The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets; they are collateral damage. And blowing up planes, trains, markets or buses is not the goal; those are just tactics.
The real targets of terrorism are the rest of us: the billions of us who are not killed but are terrorized because of the killing. The real point of terrorism is not the act itself, but our reaction to the act.
And we’re doing exactly what the terrorists want.

Whether the terrible incident of September 11, 2001 was foreign or domestic terrorism, whether it was solely the plane or the plane timed with well placed explosives is irrelevant. Our society has dramatically changed, some say irrevocably. We were a better America when we could trust our government. We were a better America when the police were not the enemy. We were a better America before Civil liberties were taken away.
