The enchantment that keeps Hogwarts invisible to Muggles must have some significant limits.
Picture this:
A couple’s driving through the highlands of Scotland, May 2nd, 1998. “Brimful of Asha” is playing from the discman through the tape adapter. They spot some old ruins in the distance and decide to get out and take a closer look. Suddenly they see diffuse flashes of colored light fill the sky, enormous indentations in the earth appearing, and they hear what sound like cries and explosions, but as one might hear them through a telephone under a quilt: muffled and distant and filtered. A tree falls over in the woods nearby.
