My Dad and his WW2 Air Force buddies

My father, Warren Westcott Grant, served 2 years with the Army Air Force during World War II as detailed here. I've recently been going through some old boxes and scanning all his old photos and came across these. I assume they were taken in 1945 when my dad was stationed at the Army Air Force base in Amarillo, Texas for his flight training.

Ray Garrett became a good friend of my dad and they maintained a friendship after the war. Ray's Aunt Bea Garrett became a friend of our family too and often stayed with us when she was visiting from Florida. Ray married Lydia  (I remember  Christmas cards signed "Ray and Lydia Garrett") but I don't know anything more about them.
As of now, I do not have full names for Goode, Gus, or Paul. I think because of my father's month-long emergency leave during his flight training, he was in two different units at Amarillo. The first was "Group R, Sqdn 251" and the 2nd was "Sqdn W 3701st AAFBU Amarillo". This second designation was on his discharge papers, the first came from his personal address book.
