Reasons it was an accident or some crazy person.
1. It hit an apartment building. 50-floor building on Upper East Side.
2. It hit middle of the day. Its a residental building, so chances are nobody would be home (from what I hear, these are million dollar condos).
3. The "small fixed wing plane" hit the building and "bounced off"...doesnt sound very effective for a terrorist.
All this was established within 15 minutes of the crash.
"There was a mayday, FAA reports, from the pilot involving a problem with fuel before the aircraft crashed into the 50-story high-rise on Manhattan's East Side."
Didnt the FAA say just before this that the plane was not in contact with the tower? This is why athletes should not fly planes...
