Engineerfag here concerning SW Flight 1380 engine failure: a fellow engineer in the office worked for GE engine div. Says it is impossible that a fan blade pierced the engine case or that shrapnel broke a window or that any shrapnel left the engine housing. They are designed far beyond normal 3x engineering safety factor. They have multiple layers of Kevlar around the engine housing he said.
He's not into Q and he hadn't heard of the incident but overheard me playing the news video (alleged passenger said row 17 many times which is curious as well but I digress..) and he said "WHAT? No. That's not impossible. We tested every possible scenario and that can't happen. Something else could have went wrong but the fan blade did not fly through the housing and it definitely didn't pierce a window."
Meant to ask him before he left, but experience tells me they would likely harden the engine side windows and wrap the passenger bay by the engine in Kevlar or another similar protection as well because the way he balked about piercing that particular window was kind of telling. My son is an aerospace engineer he just graduated I will ask him too.
Checking….
