the astronaut or cosmonaut in charge to dock the Progress without the aide of any sort of telemetry or guidance. However, the Russian Space Agency's results blamed the accident on crew error, accusing their own cosmonaut of miscalculating the distance between the Progress and the space station. The Russian Space Agency's results were heavily criticized, even by their own cosmonaut Tsibliyev, on whom they were placing the blame. During his first press conference following his return to Earth, the cosmonaut expressed his anger and disapproval by declaring, "It has been a long tradition here in Russia to look for scapegoats." The accidents also added to the increasingly vocal criticism of the aging station's reliability. Astronaut Blaine Hammond claimed that his safety concerns about Mir were ignored by NASA officials, and that records of safety meetings "disappeared from a locked vault". Mir was originally designed to fly for five years but eventually flew for three times that length of time. During Phase One and afterward, the station was showing her age—constant computer crashes, loss of power, uncontrolled tumbles through space and leaking pipes were an ever-present concern for crews. Various breakdowns of Mir Elektron oxygen-generating system were also a concern. These breakdowns led crews to become increasingly reliant on the SFOG systems that caused the fire in 1997. SFOG systems continue to be a problem aboard the ISS. Another issue of controversy was the scale of its actual scientific return, particularly following the loss of the Spektr science module. Astronauts, managers and various members of the press all complained that the benefits of the program were outweighed by the risks associated with it, especially considering the fact that most of the US science experiments had been contained within the holed module. As such, a large amount of American research was inaccessible, reducing the science that could be performed. The safety issues caused NASA to reconsider the future of the program at various times. The agency eventually decided to continue and came under fire from various areas of the press regarding that decision. Attitudes Attitudes of the Russian space program and NASA towards Phase One were also of concern to the astronauts involved. Because of Russia's financial issues, many workers at the TsUP felt that the mission hardware and continuation of Mir was more important than the lives of the cosmonauts aboard the station. As such the program was run very differently
