I am José Vela Díaz daughter. I am trying to investigate my father's biography as a pilot. I am receiving the appreciated help of Dr. Carlos Lázaro, an historian at ADAR.
Mi father was hit twice. One of them, quite serious. Perhaps this is the one you mention.
Mi father was nominated Lieutenant in 1938. He was promoted to captain in 1939, but this was never officially published. He was in the first promotion of pilots in Kirovabad.
ADAR may inform you about some more details.
Why are you interested in that?
Please feel free to get in touch with me for any other question I might be of help.
