A possible? name of the liaison pilot. In your link to personnel killed, in the section for
106 FA BN 155 MMH is listed Sandburg, George M., 1st Lt .
In findagrave for him it mentions he was a liaison pilot. Note the date of death is not given as June 24, so maybe not the right guy but perhaps the right unit.
