Not routine at all , thankfully
Routine from simulator training. Not routine in the airplane.... thankfully, as you say.
I’ve been twice a year for 15 years, but I still think Level D motion sims are the coolest things around.
I’m wondering if the flames were from a friction fire (metal on metal in a mangled engine) as opposed to actual fuel continuing to be fed to the engine. I would certainly think with an explosive failure like that they would have engaged the FW shutoff... but then again who knows what they actually saw in the cockpit. The fire indication in most engines is triggered by a pressure sensor in a closed gas loop... so they may not have gotten a fire warning for that engine.
It will be interesting to see how this plays out.
Pilots handled it just as they should - and made it a non event for passenger safety, just how it should have gone. Good stuff there!
