I still think the US military shot it down

The military did not shoot down the plane. Air traffic controllers were not aware that United 93 was hijacked until minutes after the plane crashed in Pennsylvania. The plane headed right toward the Washington Capitol then it turned around and went the opposite direction. I went to the 9/11 memorial museum and they had the actual 9-1-1 call with one of the passengers on it saying that they were going to take over the plane and stop the terrorists.

I also believe it's very much possible. And although understandable, it's not information they would ever reveal.

wrong

On 9/11 I was at work and I was in the cafeteria listening to the radio that afternoon. Nobody could work at all because of the situation. At one point the announcer said that a United States Air Force jet had shot down Flight 93 over Pennsylvania. Nothing more was said and there were no retractions of the story or further mention. The story just changed a day or so later to the "Let's Roll!" hero narrative.

Of course this is the kind of unpleasant thing that the Government would want hushed up. It's entirely plausible that this plane was shot down to prevent a further attack. I think this is actually more plausible than the movie-style event that has become the official story. Many holes in the official story, including Mark Bingham, the passenger who supposedly called his own mother before the counterattack and said "Hi Mom, this is Mark Bingham speaking."

Not shocking as it was mentioned the WH ordered it to be shot down but before they could, it crashed due to revolt against the jihadi's on board the plane. End of story. Anything else is just speculation and conspiracy theory after the investigation had concluded. People will say anything that they thought had happened at that moment in time.

Then you've clearly never seen the wreckage of a plane having been shot down

The 9/11 commission report was pretty clear on the fate of flight 93.

People often ask "How can I trust it?"

The answer is that men were found of the upmost integrity and honor to investigate and write the report, they just didn't pick anybody. If a alternative truth were found out, their reputations and their FAMILIES reputations would be in the gutter for generations to come. The careers of these men, who worked their whole life to attain, would be in tatters.

Democratic governments, with their duty to freedom of the press and speech, cannot keep secrets for long.

You can think whatever you want, that doesn't make factual...
And yes, it would be shocking
