I have a good mystery for Boing Boing readers.This morning at 7am we awoke to find the inner pane of our patio door shattered. When we went to bed at 10pm the window was still fine. We live on the third floor and there is no access to our patio. Since only the inner pane was damaged, it couldn't have been caused by something from the outside. The area that was damaged is not easy to get to, and I can speak with certainly that we didn't hit or strike it. There were no earthquakes (we live in SF), but the temperature did vary from 49 degrees at 9am…reached 70 degrees by 3pm…and then back to the 40's in the early morning hours.
The pane, though shattered, is one complete sheet. No glass has fallen out or in. And while there is one area that looks like an impact point, it is not pressed in and the glass is intact there.
Can anyone help us figure out what might have caused this as I'm looking at a very expensive repair bill?
