Are you talking about the thread with Mvandenbergh and tanzam75? Based on:
> If you launch from Baikonur directly into a 46° orbit, you will drop spent rocket stages on China. That is why the Russians launch into a 51° orbit, even though their launch site is at 46°.
> With a Proton, you have enough delta-v to launch into 51° and then make a change of plane to 39°.
It could have made the orbit just fine it just wouldn't be able to boost the shuttle into the ISS's plane. It probably could have brought them supplies if China agreed to allow the spent boosters to fall.
