"TEHRAN, Iran — An Iranian passenger plane carrying 168 people crashed a quarter-hour after takeoff Wednesday, smashing into a field northwest of the capital and shattering to pieces. State television said all on board were killed.""Caspian Airlines is a Russian-Iranian joint venture founded in 1993. Iran has frequent plane crashes often because of bad maintenance of its aging aircraft. Tehran blames the problem in part on U.S. sanctions that prevent Iran from getting spare parts for some planes. Caspian Airlines, however, uses Russian-made Tupolevs whose maintenance would be less impaired by American sanctions."http://www.comcast.net/articles/news-general/20090715/ML.Iran.Plane/Caspian Airlines operates Tu-154M aircraft, like the one pictured here:
