I very much doubt that there was/is an ORB for Rochester because it doesn’t appear ever to have been a RAF station. As I understand it the council bought the land in the early ‘30s for a municipal airport and then leased or sold it to Shorts with the proviso that Shorts facilitated commercial or private flying from the site. There appears to be some material at The National Archives regarding this in pieces AVIA 2/689, 1289 and 1651.

23 ERFTS, which flew from the site for about 18 months before being removed to safety on the outbreak of war was also a civilian-run school (managed by Shorts) rather than an RAF-run one. It does however have an ORB – at AIR 29/621.
