Sure it still ‘flew’. Like a rock flies when you throw it up in the air.

The NTSB consulted with Boeing for data and ran multiple flight simulations that matched radar data and the area where the wreckage impacted the water. They found that the most important variable was the exact time when the nose separated. Engine thrust, whether full or non-existent made no significant difference in the flight path. The other important event was when the left wing separated.
What have you done? Why should I believe you rather than the NTSB?
Because, unlike other investigations, the NTSB refuses to release their calculations claiming they are proprietary to Boeing, yet Boeing says they are not.
He doesn't work for the government, and his boss isn't a political appointee?
