As the shuttle was traveling at 18 times the speed of sound at an altitude of 63,100 meters (207,000 feet), Mission Control Center, Houston, Texas lost communications about 8 a.m. (1400 GMT). Prior to loss of communications there were no indications of abnormal activity with the shuttle's return to Earth appearing normal.
Now, from leadpenny's thread:

ken in texas SAW it when it went over and now realizes he saw it break apart.
Thanks for proving you were wrong.
I believe that during the press conference one of the flight managers said that they had received system warnings prior to the loss of communications.
