Wayne Hale, who became a Space Shuttle program manager in the years after the Columbia disaster, wrote on his blog Thursday about the meeting among ground personnel at Johnson Space Center as they grappled with the decision. Video of Columbia’s takeoff showed a briefcase-sized chunk of foam breaking off an engine and colliding with the shuttle’s wing, gouging a hole in the shield designed to protect the craft from the furious heat generated as it crossed from the vacuum of space into the atmosphere.
When it became clear that the orbiter was seriously damaged and likely wouldn’t survive re-entry, Flight Director Jon Harpold said to Hale and others at the meeting, “You know, there is nothing we can do about damage to the TPS (Thermal Protection System). If it has been damaged it’s probably better not to know. I think the crew would rather not know. Don’t you think it would be better for them to have a happy successful flight and die unexpectedly during entry than to stay on orbit, knowing that there was nothing to be done, until the air ran out?”
