Shuttle Endeavour again is suffering from weather delays getting back home to Florida. Finally, this morning the pair took off from California and made it to Ft. Worth Texas as it's first overnight stop. Why delays? The shuttle is a delicate bird covered with fragile tiles. Fly this through rain, or clouds, the tiles will chip, crack, break, or shatter depending on what it passes through. So despite it's ability to fly millions of miles, it's stricktly a fair-weather flier.
