Hmmmm. Much in the way of information to contend with. Thanks all, but I'm somewhat confused to whether its possible. Okay then. Let me put it this way. Would it be possible to refit a capital ship or fighter for this type of landing and combat??
Perhaps some sort of variant with a fighter/bomber.
I expect that you can, but it will still be less efficient (in terms of how much speed and maneuverability you can get for a given engine power) than a craft that is designed from the ground-up for atmospheric combat.
