I've had this happen after landing due to a medical emergency. Please remain seated so that the medical personnel can get to the patient. This after a high speed decent with speed brakes on the whole way down. And still, everyone stands up. We weren't even at the gate, they had brought stairs to the back of the plane along with the emergency vehicle(s).
