AD Medal of Honor Recipients?

Question

Who was the only Navy Aviation Machinists Mate(AD) Medal of Honor Recipient?

Answer 1

found one web site (http://www.ussarizona.org/survivors/grah... ) that claims Aviation Machinists Mate First Class Donald Alexander Graham was awarded the Congressional Medal of Honor for his heroic action at Pearl Harbor during World War 2.

But I can't find Graham's name at the official Congressional Medal of Honor web site (http://www.medalofhonor.com/ ). In fact, although there are about 20 Machinist Mate's listed, none are aviation.
