I have just added this to the map of places to fly your drone at Drone Scene:
Features include a disused quarry and medieval cultivation terraces.
In the early 20th century, commercial chalk extraction brought further, large changes to Blow’s Downs. There is evidence of a limeworks on the Downs by 1901.
The Luton-Dunstable rail link, which opened in 1858, provided transportation of lime away from Blow’s Down.
The British Portland Cement Manufacturing Company acquired the lease to the site, and were still running the works during the 1920s. Production ceased some time before the Second World War, with the chalk pit being used by the Home Guard as a training area.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 23/08/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
