Aeroflot to support the Russian program of biological weapons. This delivery channel encoded VOLNA ("wave") meant "delivering the material via an international flight of the Aeroflot airline in the pilots' cabin, where one of the pilots was a KGB officer". At least two SVR agents died, presumably from the transported pathogens. When businessman Nikolai Glushkov was appointed as a top manager of Aeroflot in 1996, he found that the airline company worked as a "cash cow to support international spying operations" according to Alex Goldfarb: 3,000 people out of the total workforce of 14,000 in Aeroflot were FSB, SVR, or GRU officers. All proceeds from ticket sales were distributed to 352 foreign bank accounts that could not be controlled by the Aeroflot administration. Glushkov closed all these accounts and channeled the money to an accounting center called Andava in Switzerland. He also sent a bill and wrote a letter to SVR director Yevgeni Primakov and FSB director Mikhail Barsukov asking them to pay salaries of their intelligence officers in Aeroflot in 1996. Glushkov was imprisoned in 2000 on charges of illegally channeling money through Andava. Since 2004 the company is controlled by Viktor Ivanov, a high-ranking FSB official who is a close associate of Vladimir Putin. Law enforcement The FBI has acknowledged using at least thirteen front companies to conceal their use of aircraft to observe criminal activity in the United States, including: KQM Aviation NBR Aviation NG Research PXW Services FVX Research Organized crime Many organized crime operations have substantial legitimate businesses, such as licensed gambling houses, building construction companies, hair salons and karaoke bars, engineering firms, restaurants and bars, billiard clubs, trash hauling services, or dock loading enterprises. These front companies enable these criminal organizations to launder their income from illegal activities. As well, the front companies provide plausible cover for illegal activities such as illegal gambling, extortion, drug trafficking, smuggling, and prostitution. Tattoo parlors are often used as fronts for outlaw motorcycle clubs. Where brothels are illegal, criminal organizations set up front companies providing services such as a "massage parlor" or "sauna" to the point that "massage parlor" or "sauna" is thought as a synonym of brothel in these countries. Examples A Colombian drug cartel, the Cali Cartel, in the past used Drogas La Rebaja, now a large national pharmacy store chain, as a front company in order to launder their drug trafficking earnings.
