BMax...C-121..Was that the "Connie?".....Got to help rebuild a C-118 from the AirForce(it was immaculate,looked like some Generals ride)...into a freighter...even had "anti-skid" system on it.....You could tell a military DC-6 from commercial(one of many ways) aircraft because back then the military used Mil5606 hyd fluid when commercial DC-6's were Skydrol...Bill R........As you said the Electra wings were departing the fuselage.......... due to vibration/inflexiblity @ higher airspeeds....as I recall they were slowed down to avoid future problems..I can say they were a miserable ride in turbulence......wings were stiff.....I must add those were fun days.....I worked on all kinds of planes and got to fly many of them along the way.....With the" aviation environment" as it is now, no way will that flexibilty be around any longer...which is truly sad in a ways........Bill...
