There were a lot of 911 details that really sounded strange at the time, and a few of them still sound strange.

There was a tape of air traffic controllers describing the events of 911, until "A quality-assurance manager at the center destroyed the tape several months after it was made, crushing the cassette in his hand, cutting the tape into little pieces and dropping them in different trash cans around the building" http://www.nytimes.com/2004/05/07/national/07TAPE.html
FAA policy does call for written statements, but the commission report noted that destroying that tape was a rather strange decision.

Le Monde (which is a legit newspaper, not Daily Mail) mentioned that future Afghan president Hamid Karzai was a consultant for UNOCAL, an oil company interested in building pipelines through Taliban territory. Which sounds sketchy, but apparently, the writer for Le Monde simply made this up.

I always thought it was funny that all 19 hijackers were identified less than an hour after the end of the attacks - and that they happened to be all of the 19 Arabic-sounding names on the passenger lists. Turns out that's kinda what they did at first, but luckily all 19 guys later turned out to solid suspects based on good detective work.
