Can the official theory of the twin tower collapses be proven with experimentation?

20. As a matter of fact

The very first report I saw live on tv, perhaps just minutes prior to the second plane hitting the building, was a guy being interviewed. He claims that he saw the 1st plane hit the building, he said it was a small commuter plane. The reporter asked him several times if he meant a regular sized passenger aircraft (747, 737, etc.) and the guy was like, "no no no, I'm certain it was a single engine small commuter plane."

There were so many incorrect reports that first day. When man sees something incredible, mind boggling, they tend to make up stories. It's how early man survived the early plains of Africa. They would sit around the fire and talk about the scariness out in the darkness. It's one main reason why man creates and believes conspiracy theories. I mean, what's easier to believe? The government did it? Or 19 men took over 3 aircraft and flew them directly into New York's most prominent skyline feature, killing 3000 people. Most of it on live television?
