They are only doable IF Third Party companies, who aren't under the same strict regulations as ED are, come forward and create those high quality full fidelity modules we are used to. Deka created the JF-17; RAZBAM are creating the F-15E and Mig-23 - we need more 3rd party companies to come forward an create high standard modules going forward. HeatBlur could, in reality, create high grade full fidelity modules of REDFOR aircraft, couldn't they?
