They apparently had a problem with the Spacehab cooling. The day before landing, they were looking for water that may have leaked out of the Spacehab. Why? How could this interfere with landing.
Here is a portion of the report from STS 104 - 16.
" Commander Rick Husband and Flight Engineer Kalpana Chawla of the day shift took turns simulating landing on the PILOT computer-based training system. Pilot Willie McCool of the night shift will get in his practice session overnight. Landing is scheduled for 8:16 a.m. CST Saturday and preliminary forecasts show excellent conditions at the Shuttle Landing Facility in Florida. If weather decides not to cooperate, there are plenty of supplies to support the crew until conditions are favorable.
Husband also peeked under the floor of the Spacehab module to look for water that might have leaked out of the balky air-conditioning system earlier in the mission. He reported finding no moisture that could contaminate Spacehab systems if jostled during Saturday’s re-entry and landing, but covered several holes in the water sub-assembly with tape as a precaution.
