The Kilo-class diesel submarines have an endurance of 7,500 miles without refueling. Where did they refuel on their trip to New York and back?
Can that be done in route?
Also note that the area was FULL of navy ships from various countries as their was a joint exercise occuring.
My personal theory is that it was a setup by the Clinton's. There were two targets on board the flight (see linked thread for details) one of which was supposed to be on Ron Browns flight but they missed him there.
There was a target drone launched to be behind the flight (see the radar tracks). If the flight's transponder was damaged (as reported by controllers) ordinance fired at the drone could have been inadvertantly targeted on the flight. Plane goes down and it looks like an accident. Clinton enemy dies and clintons go free again.
See the linked thread for rest of details. Including discussion of why the shooter didn't talk
You're assuming that the subs made a Iran-NYC direct trip. There's plenty of places along the way to stop for diesel. If they want to play it dangerously, most any ship could serve as a sub tender for at sea refueling.
