Reports from Spain indicate that Spanair's MRO system may have been infected by malware, leading to a failure to take out of service an aircraft with known problems. Reports have failed to identify the precise MRO system in use at Spanair but then-parent company SAS uses AuRA from MIRO technologies which definitely has a Windows component. Until now the fact that Windows is the target of most malware in the wild has been an economic issue. Perhaps now it has contributed to the loss of 154 lives.
