Hurricane Bawbag

Ok there's no snow. But do you see the greenhouse windows?

Those two lower panes blew out. They went up, over the top of the greenhouse, and landed one here

and one on top of the herbs. And they are completely undamaged. I have no idea how this could be possible. I've stacked them in the gulley between the garden and the house and I hope the wind doesn't get them there.
