I don't think any simulator experience can prepare you for this. BANG! -- something is wrong. Really wrong. You have good instrumentation and automation, and you know what you're doing, but at the end of the day you're still a fallible human and your ship is wounded in ways neither you nor the automation fully know yet -- and won't fully know until you try to do something, like extend flaps or even move the yoke a bit -- and find out whether bent metal, binding bearings, or severed hydraulics will stop things from happening the way you hoped -- or whether or when additional parts of the airplane will decide to take early retirement. Respect for all involved.
