If you're on about the video of the Ryanair flight TBH I'm not surprised it's underwhelming.
It seems the window failed at 15000 feet
I don't know the details of how a 737's prssurisation is scheduled but whilst it's quite possible that (as is reported) one person ended up with their head stuck in the window by the outflowing air it would (fortunately) have been a relatively benign decompression....
If the window had gone at 25-30,000 feet or above it might have been much worse.... and by saying that I maybr need to emphasise I'm not saying what happened was trivial.
