May not apply to the old 737 but a point worth remembering is that after, say, an engine detaching you will have a list of messages in front of you, scan it immediately looking for "Bleed Duct Leak", it may come three or four down the list, (possibly get a fire warning first, even though the engine has left you!), but you are dumping your pressurisation over the side so you need to fix this one first. If you don't it will lead you into a rubber jungle, emergency descent etc. none of which you need whilst dealing with "Engine, severe damage and separation"
