Just finished reading the following article:
NASA confirms that Discovery’s position helps lift station higher in orbit
A 2 page article on reboosting the ISS orbit.
Now, maybe an article was in order because it does have some interesting explainations, but the way they approached it kind of made me cringe.
I'm just curious... am I being overly critical?

Half of the article uses the following words: Bizzare, Baffled, Phantom, Puzzlement, Computer problem, etc.
Basically made a big thing out of 2 amateur (yet experienced) observers who didn't find the answer where they would expect it to. That the boost occured from firing the vernier rockets for stability rather than an actual boost maneuver.

Orbital mechanics don't work by common sense. If you burn hard enough to don't move forward--but move higher. Two craft approaching each other have to be careful. Both are actually going around in orbit at incredible speeds in one direction--so while the relative motion of craft can be "toward" and "away" from each other--they are really travelling together. If they are facing each other along the line of the orbit and both burn hard--they don't ram. One lifts its orbit--where the other actually 'feels' its thrust as a retro burn--and drops. You have to get pretty close before using more direct methods of approach.

So simple thruster action is fooling them after all.
