Some time ago two Russian aircraft, TU-134 and TU-154 crashed, falling at about the same time. Regardless of the alleged terrorist attacks, Russia was still using the old planes. Even models such as passenger aircraft in military cargo planes. Materials technology in Russia, especially for materials of war so well known that this probably caused the planes remain durable despite the ambient temperature is always cold.
An Indonesian researcher in the company in Japan tells the journey to Russia in order to attend a conference on the material.
First entered Russia via Moscow, with a large Airbus aircraft departing from Narita. Continued from Moscow to Tomsk (Siberia) with the local plane. Nothing special except Narita-Moscow long trip for 9 hours in the air and the expertise of the pilots for landing in the Siberian region in the state of the snowy winter night temperatures around -30 degrees Celsius.
Both times, enter through Vladivostok from Toyama. This time it is quite surprising. How not, the aircraft used is a little old aircraft with 4 seats per line seat, with passenger capacity of 30 people. Suitcases and other items placed in the tail, much like a small military aircraft to carry troops to the entrance out of the tail. No air conditioner, so the room smelled of dedication and heat. To reduce the heat, the pilot window must be opened if the machine is not turned on. But my doubts disappeared after the plane airborne, the engine was still pretty good and hold air temperature at -50 degrees Celsius (at that time was the fall). At that time Russia has not realized that the plane output in the 70's this (YAK-40) is also the type that crashed in Uzbekistan earlier this year after hitting a concrete building the airport.
The third time, when entered via Vladivostok from Niigata, concern has been somewhat diminished by a small plane flying Vladivostok Avia Tu-154, although this type of plane that crashed in Irkutsk Siberia in 2001.
The cars are used in Moscow, let alone in Tomsk, there are many cars in the 60's. The design box ¡| with no aerodynamis design. Even the Volga car brand that we were riding though made in the 90's, the designs still doeloe car era. Image of Russian basic science is the power possessed, they dared to produce goods / heavy machinery with specifications multiplied. The result, the goods are put up for years even if the outside looks less attractive designs.
To make the airplane / car stand in the frozen area, they should consider Nil ductility Temparature (NDT), the temperature where the material does not have the flexibility-of the material used, so do not experience brittle fracture at low temperatures. This is reminiscent of the story of the Liberty Ship that split the ship in dock in low water temperatures. This may be a valuable lesson for them. Or the ship Titanic which sank after hitting ice bengkuhan, who allegedly also because cold temperatures cause the brittle fracture 35 F easily happen, might this also be a material consideration for them. What is clear, will not be easy to design equipment in extreme weather in Siberia where the temperature can reach -35 C in winter and 35 C in summer.
