Congrats on the win!
Nope...the original ENT was never designed to be aerodynamic. Can't fly or maneuver within an atmosphere.
See the book "The Making of Star Trek" by David Gerrold. I'm pretty sure it's considered somewhat definitive on the subject. Jeffries knew what Roddenberry's limitations on f/x were and ran with the "no atmosphere" rule (short of what was shown in "Tomorrow is Yesterday", I suppose). The grey lady was never intended to be flown in an atmosphere for ANY length of time short of the accidental post-time-travel dipdown in that episode which led to the destruction of Captain Christopher's jet, and she would NEVER be capable of LANDING on a planet.
