STOCKTON — Jose Hernandez’s voice still carries a note of awe at what he accomplished 10 years ago this week.Forever, he will bring with him the memory of taking off his seat belt and flying across the cabin like Superman when Space Shuttle Discovery had finally delivered him and his six crewmates into the heavens.He remembers the amazement at being one of about 500 people out of the world population of 7.5 billion to be able to look down at Earth.
