Besides, before we go off adding weight to the Shuttle fleet and seeking stronger glue, we may want to determine that tile displacement is indeed a problem. The tiles may have performed perfectly.
An article in this morning's Toronto Star (www.torontostar.com
)covered some speculation that an ice ball may have formed at the wastewater vent and caused damage to the leading edge of the left wing when it broke free. Apparently this ice ball problem occurred at least once before (I think with Challenger in 1984) and the ice formed a basketball sized chunk. Heaters were installed after the incident to keep the vents from icing over but there may have been a failure. It's just one of many possible leads that needs to be investigated.
