ok so here is what i was thinking when a space ship enters the atmosphere the reason for the high impact velocity is that the air is spinning at 66000mh AND that to keep an orbit you need certain speed with is different from the earths rotation... now if you slow down/speed up to match earths rotational velocity you start to "fall" faster then you could match the required speed now here is my idea and let me know guys if you see something wrong with this theory lets assume you have enough fuel to compensate for the gravitational pull , in other words you use your engines to "hover" till you reach the required speed to sink in to the atmosphere.. would this work ? secondly the earth poles the atmosphere is not sniping obviously because those are the axles, so could you not just fly the thing there and enter the atmosphere there with out any major air resistance ? (again of course compensate for gravity on approach with engines) then once you enter the atmosphere slowly you just use normal jet engines to fly where ever you want to land as you dont have the high velocity entry, the design do not have to withstand the heat and pressure of current landings, the spaceship could be designed like a conventional airplane with jet engines again dual engines, jet engine for air, rocket engines for space did i miss anything ? is this possible ? it seems way cheaper and safer to design such craft.. no ?
