Beja Airport, Portugal: sonar buoys chutes - sonobuoys are used in anti-submarine warfare and submarine rescue - there are two main types, active buoys send out sonar pulses, which reflect off of the submarine, and the return is datal inked back to the aircraft, passive buoys listen for any radiated noise from the submarine contact -  hydrophone sensors and stabilizing equipment are below the water surface, the buoy relays acoustic information from its hydrophone via UHF/VHF radio to operators on board the aircraft - Lockheed P-3 Orion aircraft, a military derivative of the Lockheed L-188 Electra.

Left abandoned outside a hangar to the elements, this huge cargo plane is slowly becoming overgrown with moss and algae, the dirt is streaking down its hull, and the crevices around the engines are being used as nesting sites by birds. \n\nThe plane is monstrous however, 4 gigantic propeller engines - 2 per wing - power what was obviously once a beast of an aircraft, the size easily allowing it to carry troops, supplies, even vehicles in its hold. \n\nNow it stands as a piece of aviation history, obviously disused and obsolete, the tech has been surpassed by more moden aircraft.

Lisbon, Portugal: Ram Air Turbine (RAT)  is a small propellor that will deploy in a serious emergency to supply emergency backup electrical power to the aircraft. Usually this happens after all main engines and the APU (auxiliary power unit) fail. Behind the two-blade propeller a hydraulic pump can be seen, besides power, the RAT provides emergency hydraulic pressure. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft. It may be also called an air driven generator (ADG) -
