It took a careful, knowing eye to perceive the subtle changes in the shades of the black plasticrete rushing below the aircraft's landing gear. Except for Jason Chase, who forced himself to watch, the pilot was the only other person who noticed. Feeling her craft pass safely over the spot, she offered a silent prayer of thanks. Though the scars had long been covered over, Chase could see them as as he had in the days after the accident. There was one long, jagged fault, one hundred meters or so in length, and a second one running parallel. That one started a short distance after the first, but ended almost immediately at the point where the metal that carved it out had bent and shattered.
