I could imagine if there was someone that was just a natural at it they
would get an email...????

Yes on the up and down. But if you want to catch up to another
airplane you do give it more throttle.

So basically the way an airplane operates?

I found it astounding to learn that during the first NASA manned
docking test, the guys would give it some throttle and get farther
away from the target. Nobody had thought it through.
More throttle == faster == higher orbit == slower orbital period.
So you have to slow down to catch up if you want to dock. If you
are behind, you slow down until you get ahead and then speed up to
raise up and slow down...

It's not quite like shooting a bullet. There is a window that they
can maneuver within. It may have to do with the amount of propellant
carried in the "garage" attached to the back of the crew dragon.
There also has to be enough left in that to de-orbit.
I saw a series of diagrams somewhere (maybe on the SpaceX web site?)
that illustrated all the various maneuvers at the different stages.
The approach to the ISS is interesting in that there is an exclusion
zone of sorts all around the ISS. They need to target to outside that
zone until they make their final approach. Once they are in a
parallel orbit just outside the exclusion zone, they can rotate and
maneuver into the docking station. The crew dragon (and the cargo
dragon) is that the whole operation is autonomous.

Guy on radio was saying SpaceX crew capsule has to be launched at a
specific time to rendezvous with the ISS, sounds like shooting a
bullet. Same guy said Boeing design will have a wider launch window
because it is more maneuverable. Looking at photos they don’t seem
that different. Does this sound right? Main difference seems to be
the way they land, in water or on land.
Not sure what happens to Boeing capsule if collapse of air travel on
top of 737 Max fiasco spells the end of Boeing as a company.

If you're not on daylight saving time, you know what to do.
