Did some tests and there are some problems when using the data tables for the Hubble rendezvous. the trajectory to the HST is not the same as illustrated on the flight data files and it uses more fuel. Im not sure what I was doing wrong but I did it by the numbers and it still makes the same mistakes. Give me a reply so I can reproduce the bug so that you can fix it, right now its late.
all and all the ISS rendezvous is flawless, I haven't tried Mir and the SMM though
