A report on the Columbia Shuttle disaster is expected at the end of this month.
Relatives of the seven astronauts who died aboard shuttle are anxiously awaiting what to know what it says.
Jon Salton -- brother of astronaut Laurel Clark -- viewed the video of an impact test that showed a chunk of foam insulation knocking a giant hole in shuttle wing parts.
Salton says watching the video was hard.
But he says it didn't make him angry -- it just made him sad.
He says NASA officials who didn't believe foam could do such damage -- quote -- "really missed the boat."
Most family members who spoke with The Associated Press say they
simply want the shuttle fixed and able to fly again more safely.
Some say they appreciated the candor of the accident board.
