while the proximate cause of that shuttle burning up being caused by tile damage might have been averted by a tighter maintenance schedule for various components leading to the ultimate tile damage on takeoff. It appears more to have been a lack of vision, literally. the quote by the by then rotten head of NASA who somewhat sheepishly said in news conferences which I happened to catch on the satellite NASA channel and I don't think widely aired and they have since removed, that we decided not to look at the tile damage while in orbit because we couldn't have fixed it anyway. I expected him to resign at that moment and was dismayed to learn they would allow him to finish out the year and collect a pension. needless to say, the arm was reconfigured to contain video and a tile repair kit and provisions for EVA are now standard equipment. I find it hard to believe that after years of tile damage on takeoff and intense study by thousands of people over years that no one could have challenged the conventional wisdom that it would be better not to know if there were any serious tile damage in orbit but that's apparently how it was. time and time again Leo gets broken down and built up again while adding a feature or fixing a bug and often both at once. any number of projects suffer from lack of vision at the top and at the bottom. Leo has been a great example of successful feedback at both ends of the loop.
