My favorite line was in the National Post,
"Theoretically, the only problem with airplanes and tanks being invisible is that the light no longer goes through them; it goes around them, thereby rendering the pilot blind."
Great. And how are they going to fix this sort of problem? If it really works, any kind of wave would wrap around the object, so you couldn't even use radar to figure out where objects are if you're operating a moving vehicle.
