I'll brain dump what I know before I go.
My father worked on the Spitfire Mk 1X production line at Vickers Armstrongs (now Jaguar) during 1943. At the ripe old age of 16 he was team leader on assembly of the tailplanes, assisted by two even younger girls who had come down from Sunderland for the war effort. When he could wangle it, he would get to drive the tractor that towed the completed planes over the Chester Road to Castle Brom airfield for their test flight. On reaching 17 in February 1944 he joined the RAF, and I presume that he was based at the airfield. Following his third flight he was found to be red/green colour blind, so transferred to the navy.
During WWII there were american servicemen based at the airfield, and two were billetted at my grandparents council house on the Chester Road. One was a red indian called Jim.
My own memories are firstly of riding my bike down Park Lane to a sale of surplus equipment from Nissan huts sometime around 1963. Once construction of Castle Vale had begun in 1964 it opened access to an RAF residential road that cut the corner from Kingsbury Road down to Chester Road, which allowed a group of us lads to storm a nearby pill box on the airfield.
In 1965 my widowed grandmother moved to the newly built Argosy House tower block just off Farnborough Road. From there I was able to walk on the remainder of the runway, which was definitely concrete and not tarmac.
During the summer of 1972 I worked for Dunlop labelling tyres at their storage facility in the huge flight shed at the bottom of Park Lane.
Sadly, it's all now gone.
