The Russians have proven that it isn't just the US and France that know how to send spacecraft off course using software.

An article on MSNBC claims that the cause of the off-course landing of the most recent Soyuz station was an as-yet-unidentified software glitch.

Of concern is the fact that this is the same guidance computer and software loaded on the Soyuz capsule that will bring the two occupants of the ISS home when they need it.
