          Ultimately, engine developers need to create low-cost options. Suder says that may present challenges to manufacturers because eliminating non-essential engineering while maintaining high reliability for expendable engines is not something the jet turbine industry is well set up to do. "I only need this thing to last for 20h, I don't need 10,000h of life in it," he says. "The tools aren't sophisticated to really accurately predict only a few hours of life, so we actually overdesign everything."
          very good summary of a remarkable analysis. We have posted the acquisition announcement at the time.

                mig-31bm - Hard to say. There is very little that is known about it at this time.
