Re: UA328 engine explosion at DEN

Isn't it a bit overreacting of all parties involved by immediately (temporarily) grounding an entire fleet of planes (the 777's with this type of engine) after an engine failure? The plane landed safely and everybody walked off the plane alive. Yes, it is a serious incident. Yes, it needs to be inv...

Doing nothing on the MAX with active MCAS would have killed the PAX even faster. This is not strictly accurate in reg...
