"The evidence comes from an old magnetic tape recorder that is part of the Orbiter Experiment Support System, sources said.
It shows an unusual temperature increase in a key sensor just behind the leading edge of the left wing near the spot where foam that fell from the shuttle's external fuel tank is suspected of striking the shuttle, just 81 seconds into the flight.
The temperature spike happens within the next 40 seconds. Usually during this phase of flight, the temperature would be decreasing or holding steady, sources said."
