Thanks, I see it now.A window panel on the blue cabin shattered - It was tempered glass. The other panels are likely tempered glass as well. Photo is on twitter.. and in this thread somewhere too
ETA: here you go... my remix

But no, we don't have reports of that glass falling on any guests.
The manufacturer website confirms that the main windows on the Omega V are polycarbonate. I don't think they're selling Omega IV's anymore, so I couldn't find any info specific to that model.
