1 dead after jet blows an engine; woman nearly sucked out
IMO This is why you keep you set belt on all the time, there really no safe zone when flying Rapid decompression bad enough but with hole in plane like giant vacuum cleaner till pressure equalized. One of many reasons to keep your seat belt latched.
Looks like fan Blade or disk failure (usually Fan blades are contained in side cases) which shoots blades and scrapple in all direction of rotation path faster that bullets with poundage behind the force. You can bet they will be looking at Hours and maintenance on GE and associates Engines on those airplanes.
Also you really don't want to be setting inline with Fan or turbine disks. It's Rare that they fail, but when they do engine parts fly in all directions when they penetrate cases which are harden and re-enforced but they can. I seen this few times working around Jet engines for 40 years and of course several bird strikes.
