I've recently noticed that if one of your pads is damaged or destroyed, while it shows a trashed pad graphic in your spaceport (usa_port.dat.36.png for instance), if you click on the launch facility, that screen comes up showing a graphic for a healthy one (lfacil.but.0-5.png). This is just esthetic of course, but it might be handy if we created an lfacil graphic showing a damaged pad.
