If this truely was "Turbulence", why is the FBI involved at all?

Probably because the cause has not been established yet. You don't think the FBI should be involved?

On 9/11, when it was recognized co-ordinated attacks were taking place, the government shut down air traffic all over the country, because they didn't know whether it was over. After this crash, NYC airports were shut down, as well as the tunnels, but re-opened in a couple hours. They must have strongly believed that there was no terrorist involvement(because of lack of intercepted communications pointing that way in days prior?), or they would not have bet against this being a new wave of attacks, even if they didn't care about anything except playing CYA. That said, I think I'd feel safer about flying any type of airplane or airline rather than flying out of JFK.
