On an Alaska Airlines flight traveling from Boston to Los Angeles, Clara Daly was seated when a flight attendant yelled out over the loudspeaker, ‘Does anyone on board know American Sign Language?’

15-year-old Clara pressed the call button. When the flight attendant arrived, she described the circumstance.

She explained, ‘We have a passenger on the plane who is blind and deaf. According to PEOPLE magazine, the customer appeared to desire something, but because he was flying alone, the flight attendants were unable to discern his needs.’

Clara knew she could finger spell into the man’s palm because she had been learning ASL for the previous year to cope with her dyslexia.

She then unbuckled her seat belt, made her way to the front of the aircraft, and kneeled by Tim Cook’s aisle seat, who was 64 at the time.

She gave him a kind handshake and sighed, ‘How are you? Are you alright? The cook requested some water.

Clara returned to her seat when it did. He wanted to know the time, so she returned a little later. On her third visit, she made a point of stopping and staying.

He was in no need of anything. He wanted to communicate because he felt lonely, explains Clara.

They continued doing that for the next hour. She discussed her family and her future goals (she wants to be a politician).

Cook told Clara about his growing blindness over the years and related tales from his career as a traveling salesman. He couldn’t see her, but he said she ‘looked intently at his face with such kindness.’

A flight attendant told Alaska Airlines in a blog article that ‘Clara was outstanding.’ She was such an angel, and you could tell Tim was thrilled to have someone he could talk to.
