Sensor Circuitry Malfunction on Shuttle: What Went Wrong?

[abercrombiems02]

Does anyone know what technically went wrong in the sensor circuitry on board the shuttle. All I know is the liquid H2 sensor shuts off the external booster when the fuel becomes critically low. During the pre-launch test the sensor indicated the booster was low on fuel, however the tank was completely filled. Does anyone know what caused the sensor to incorrectly measure the amount of fuel in the tank?

Bush's poor NASA budgets have the blame. The deviation of money to Iraq's war has this kind of consequences. Apart of this I don't know.

I've always used "Spaceflight Now" as a source for information regarding launches. There's a good explanation of what the problem is all about here:

A later report seems to indicate there's a problem with the grounding of the sensor. You can read that report here:
