Flight diversions are most often gas-and-go with no deplaning of passengers. However, a diversion may happen because of an emergency on the plane or an emergency may result from the diversion, and in either case emergency response and possibly victim and family assistance may be involved. Diversions may be to an airport that does not typically handle the size or type of aircraft involved or the number of passengers all arriving at once, especially if medical or other emergency response is required.
