One thing that hasn't been highlighted in the press conferences is that the astronauts did NOT see most of the sensors dropping offline. The onboard equipment isn't able to easily display all the thousands of sensor points throughout the ship. The crew will customize thier displays (possible with the new MEDS) to display what they consider important, and sensors like those that went offline aren't *normally* that critcial to flying the ship.

The only one that they would've gotten notification of was the tire pressure going offline. that would show up on their caution & warning panel, as well as annunciate the master alarm.

BTW, it turns out the file I uploaded was an early draft of the presentation. The final version is available at spaceflight.gov. and contains more information (and doesn't require powerpoint to view!).
