OverRun,
I'm happy to try and build the model you suggest and I am even happier to have some academic feedback. I'll work on something over the next few days and I will send you something via PM. If you are happy with the model I will happily post it on the open forum.
Ref ac types similar to An-124-100 the Lockheed C-5 is the obvious choice for comparitive details. Unfortunately I can't find the relevant performance data for the C-5 either. Very frustrating.
Regards,
Tragic Rug
