That does happen, but it's SUPER-RARE! Like one in a million chance for them to hit in mid-air, but there are actual battlefield specimens found. To find one of those, especially on a battlefield, would be a centerpiece of my collection. I've known of a few also surfacing over the years that probably hit in the ground, but a mid-air collision I've only seen in relic books. The one pictured on the site looks like one I've seen in relic books, because it was a dead-on collision like that. Wow, I've dreamed of finding one for years, but I know that will most likely never happen.
