You mentioned yaw thrusters in your comments. There is some bleeding of fuel in the front of the orbiter before reentry. I believe the yaw thrusters are drained as a safety issue, wanting to eliminate fuel in that area. Look, perhpas someone with nore knowledge in this area can explain exactly what is drained, and from which forward system. I'm only trying to relate and make sense out of what I read.
