Russia: Aeroflot IL18

The Ilyushin Il-18 is a large turboprop airliner that first flew in 1957 and became one of the best known and most durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and (to a lesser extent) civilian capacities. The Il-18's successor was the long range Il-62 jet airliner.

Germany: Lockheed Martin WC-130

Ever wondered how the US Air Force cleans its planes? Here’s one way: They use a giant shower on a runway — or a plane wash if you must. Here you can see it cleaning the salt accumulated on a Lockheed Martin WC-130 Hercules after flying through storms over the Gulf of Mexico. The Lockheed WC-130 Hurricane Hunter is a high-wing, medium-range aircraft used in weather reconnaissance missions. The aircraft is a modified version of the C-130 transport configured with palletized weather instrumentation for penetration of tropical disturbances and storms, hurricanes and winter storms to obtain data on movement, size and intensity.
