Narrative:
At FL180 we experienced a rapid depressurization and executed an emergency descent to 10000'. We could not control the cabin pressurization. Both the rapid depressurization and emergency checklists were accomplished. We leveled at 10000' and proceeded to lga for a normal approach and landing.
