    These deploy in case of total engine failure to provide enough thrust to get the aircraft to the next airport.

      Yeah, an Auxiliary Propulsion Unit. Seeing one deployed is pretty normal, but when an aircraft has two or more out at the same time, you should be leery of deeper problems with the main engines.
