Re. P and P’s bit about the VR augmentation – it would be a superb thing to do. In fact no goggles are needed. I have already used a smartphone app with the kids on a Gruffalo hunt through the woods, with animated snakes appearing on logpiles and owls in trees etc. All you need to do is point your phone in the right direction, in camera mode, and the images are overlayed onto the live background. The effect is totally absorbing. Seeing the crew at stations, for example, flak bursts, damage, with sound… it could be very effective indeed. Or imagine watching a gaggle of Heinkels intercepted over DX. The possibilities are endless.
