I tried the refueling training mission in realistic mode, but have problems.
First, when being right behind the tanker, I have trouble keeping the right altitude.. .its almost as if the tanker is producing turbulence.

Second, I tried to open the refueling door (shift+ctrl+r), and expected that a) I get better control (like when you put the gears down), b) the lights in the cockpit (where the NWS light is) would light up and c) I could see the opened door from outside. But the key seems to have no effect!?

Any hints on what I�m doing wrong?
