Sans,
You cannot seem to take a hint.
Either you cannot help yourself and fall prey to FH who sometimes makes a provocative post and you feel compelled to respond with a full broad side of grapeshot and shrapnel.....or you really wish to be argumentative.
Even the GAO and other government publications point to the design of the Osprey creates issues seen as questionable, unsafe, or at the very least awkward. That the Osprey is burdened with some flight characteristics that beg questioning is going to stay with it until the whole fleet finds itself in the Arizona desert mothballed.
I would suggest posting a laundry list of incidents and accidents for a particular type of aircraft in an effort to bolster your position on the Osprey is fraught with peril. Take the Bell UH-1 series that came into being in the late 50's....was the first turbine powered helicopter....and is still beating the skies into submission as we speak in just about every part of the world in some variant or another.
It too has an impressive list of mechanical failures, short comings, and in the end is an Icon and turned out to be one of the most reliable helicopters every built.
The Osprey has a long....long way to go before you can say it shall be the success legacy helicopters are. I won't be around for that discussion as it will have to take place in 2065-2070.....if we use the UH-1 /47/53/60 families of helicopters. So at best....your claims are premature by about a half a century.
