The initial shuttle damage state is still being recovered via analysis.

Whether the modifed yaw re-entry could have saved either the craft, or brought the crew down to at least a safe bailout speed, will then be determined.

Whatever the results of those analysis, it is clear that at a minimum the modified yaw re-entry should have been used.
That failure will analyzed, along with the failure to allow stand the request for imagery.

The possibilities of the development and use of other re-entry paths will be looked at, and looked at in depth.

Actual manned space flight in the real world is much more difficult than many space enthusiasts believe that it is. But we all live in that real world, and ignoring those difficulties there leads to losses of craft and crew.
