Two men who have been best friends for 60 years have just realized they are actually brothers. It’s reported that Alan Robinson and Walter MacDonald met in the sixth grade at a school in Hawaii. They have been best friends ever since.

Alan was given away for adoption soon after he was born. And Walter never knew his father. (3) So recently, they made separate attempts on DNA-matching websites to discover more about their ancestry. Walter was astonished to find that he matched with website user Robi737. He knew immediately that this was his best friend Alan, whose friends call him Robi and who flew 737 airplanes when he was a pilot. (4) The pair were born to the same mother 15 months apart.
