 When all you have to navigate with is a computer that takes
 a full second to multiply and a telescope that could probably
 only sense the horizon it gets a bit harder.. 
I agree.  The principle behind a rocket engine is obvious.  The rest
is just minor improvements.  Attitude and trajectory control is much less
obvious.  Doesn't take long for a gyro alone to drift enough that your
V2 misses london entirely.  A Minuteman is a lot more accurate than a
V2 and has a longer boost phase.  Anyone know what its attitude instument
package was?
