I don't see how the discussion about crashes is relevant in this thread related to the sale of these two unique birds. Both the Su27 and MiG29 have crashed at various airshows over the years, most (if not all) of these crashes can be traced back to pilot error. All military aircraft suffer attrition rates in normal operating conditions and the russians do have a track record of being somewhat unruly at airshows (and in general). Like that norwegian P3 Orion over the north sea, about 10 years ago or so, that encountered a Su27 intercept and the Sukhoi pilot went in so close he struck the recce plane with one of his tail fins. Both aircraft and all crew survived that incident, but the norwegians swore that the russian was drunk! That may very well have been the case.
Back on topic, those birds are unique and deserve a worthy owner. I hope they find a good home and a owner who isn't afraid to fly them at airshows.
