NASA: Gash Penetrated Entire Width of Heat Tiles
A close-up laser inspection by Endeavour's astronauts Sunday revealed that a 31/2-inch-long gouge penetrates all the way through thermal tiles on the shuttle's belly, and had NASA urgently calculating whether risky spacewalk repairs are needed.
They're calculating whether to repair it? The gouge goes all the way through the tile "exposing the felt material sandwiched between the tiles and the shuttle's aluminum frame." You don't take the chance, you fix the tiles. Can you imagine the uproar if they don't fix it and the shuttle burns up on re-entry? What about the crew, NASA is willing to risk them?
This is a no-brainer, stop calculating and repair the damage.
