Shrapnel from the blown engine shattered the window. That doesn’t mean she was sitting by the engine.
It will be interesting to find out where she was actually sitting. And if she had her seatbelt fastened (which gives credence to the admonition to always keep the seatbelt fastened while sitting in an airplane).
I like window seats, but do keep the belt fairly tight. I don’t sit by the wings/engines.
