Here's a QuickTime movie of our highest-speed impact. WARNING: it's 160 MB, so it's best to download it before viewing. First you see Dan Durda (the PI); at the end you see the crane operators A-Ray and Chris enter the view. Unfortunately, the sound is out of sync in this video, so just ignore it. And no, these ~3000-lb balls don't shatter, even though the impact speed was greater than 1 m/s!
