Those of us who can see and hear without any impediment often take navigating the world for granted. You can communicate fairly easily, and though traveling has its stresses, you're less likely to be completely dependent on another person to get through the experience.
This story of a blind and deaf man taking a flight by himself has been moving people online—a woman named Lynette Scribner posted the story on Tuesday to her Facebook page and it went quickly viral. The man's name is Tim, and he was escorted aboard by a companion who communicated with him by doing sign language in his hand so he could "read" it by touch. But he was continuing on the flight alone.
