I've made these screenshots from
XV490's interesting post #640 about the tests on the effects of aircraft noise on covert operations at Latimer House.
The aerial photograph below can be found way back in this thread somewhere. What I have noticed now is the date that the recce was made by the RAF which was 6th May 1942. I suspect specifically in connection with the planned flight by the Halifax to Bovingdon the following day..........?
Note unfinished state - threshold R/W 04 and typically several dispersals at Whelpley Hill still to be constructed, runways not marked. American Air Museum in Britain.
