The final seconds of flight exhibited extraordinarily precise maneuvering. The plane came in between the Navy Annex (large rectangular complex of building wings in the upper right) and the VDOT antenna to the left of the Annex. It then proceeded at full throttle across the cloverleaf, clipping lamp posts along the way, and made a final corrective maneuver (not available in the truncated flight data which is missing the final few data frames). One witness told us that he thought the plane had actually bounced off the heliport. He was situated on I395 in a semi truck.
Well obviously the plane did not 'bounce off the helipad' as there is no physical evidence of that.
Not even sure why you would mention that. Is that a "precise" manouver in your estimation?
The rest of your post seems to have you trying to tell us that wherever the plane went and whatever it did was precisely what the pilot intended.
