I bash the decision to use a COTS operating system for a critical system where failure can cause fatalities. Too many think they can use Windows for everything, which is of course what Microsoft pushes. Sorry, Windows should NOT be used in some circumstances. Neither should other off-the-shelf systems.
Then you'd be pleased to know that the maintenance records program is not considered a critical system, and that even if the ground crew had properly used the maintenance records program (the computer operated, by the way, it was just slow - they were too impatient to wait) it would NOT have affected or stopped this tragedy.
This is pure, unadulterated FUD on the part of the anti-Microsoft legion around FR, taking some twisted pleasure in the death of 154 people. Sick.
