Israeli Air Force Has Huge Belgian Balls

Speaking of huge, impressive balls, Reuters reports that a Belgian firm called Barco is delivering its first order of eight, brand new, 360-degree flight simulators, each of which is a 3.4 meter-diameter cast acrylic sphere. The sphere is ringed by thirteen hi-res projectors, whose images are all laser-stitched together or something in some suitably seamless way.
Alls I know is, 10-foot-wide acrylic sphere screen. Also, Top Gun? Really?
