Obtaining permission to do this would normally be impossible unless the street had been completely closed, for example as a set for a feature film, but since England was in Lockdown 2 at that point, I felt it might be possible & sought the assistance of Adam Bailey of EK Digital, a friend & past infrastructure colleague based in London.
Adam managed to achieve permission from NATS (National Air Traffic Services) & both the Metropolitan & diplomatic police to unlock the restricted airspace above Bond Street, our client arranged for the notification of all the building occupiers below our pre-agreed flight paths, & after waiting a few days for the weather, we finally took to the skies on the last day of the lockdown.
