Interesting.

It is common in the engineering sciences for advanced theoretical ideas to greatly presage their practical implementation, and ideas for highly changeable wing shapes are such an advance waiting for the right time. It is interesting to note the bulk of aeronautical advances we enjoy now actually spring from the hurly-burly days of WWII, little items we take for granted like supersonic airfoils, turbine powerplants, inertial navigation, and airborne radar. Not sure what it will take to get changing wings and other known advances into production but anything worthwhile is generally adopted by a forward- looking company when the time is right. Since war is the strongest motivator, maybe it is a good thing we are a bit behind on changeable wings. One thing that should help is the advent of very small and sophisticated stability computers, such as we see on the current crop of UAV helicopters and multi-copters.
