It was in woodshop, and someone (I don't remember who) was sanding a piece of wood on an oscillating vertical sander, when it caught and was flung into the top of a nearby band-saw. Thankfully the band-saw had a large upper structure so the wood hit only it - and not any person. But it was Loud.

Now, in Robotics, there haven't been any serious incidents, just the usual scrapes. Ironically, First Aid is in the cutting drawer...
