Earth is bigger than the moon. Eagle had to reach Lunar Orbit. SaturnV had to reach Earth orbit (and cope with atmospheric drag) and also then ESCAPE from Earth orbit. Eagle did not.

I think the air resistance must be huge. A cyclist going 20 mph expends 90% of his or her energy overcoming are resistance. Of course cyclists don't have to overcome gravity (I refuse to cycle uphill) but I'd still wager that air resistance will be significant.
