Would you care to provide a probable scenario where an engine separation would cause a dual bleed duct leak (and resulting pressurization failure) on B737?
No, I really can't. We had the scenario given to us in the B744 SIM where an inboard engine broke away, up came all the messages, including fire warning at the top, it was played through to the end with us not jumping on the bleed leak, just to emphasis what would happen, I thought this might carry over to the B737 but obviously it doesn't!
I think this would be a good time for me to quietly slip out the door, unnoticed!
