Why can't you do that [rockets all the way down] in an atmosphere?

Sorry, what I meant to say was that the sort of design used for spacecraft to land on the Moon (whatever shape you want, plus rockets - see Surveyor or the Lunar Module) couldn't be used to land on the Earth: the sort of speed you'd have when you hit the atmosphere would destroy the spacecraft long before rocket engines could slow you down.
