  • The episode opens with a verbatim Biggin Hill ops-room exchange showing controllers vectoring squadrons live into combat.
  • That snapshot demonstrates how controllers directed multiple squadrons simultaneously through standardised phraseology.

First Integrated Air-Defence Network

  • The Dowding system combined RDF, Observer Corps, filter rooms and ops rooms into the world's first integrated air-defence network.
  • Centralised data at Bentley Priory and standardised sector ops let controllers vector fighters efficiently before bombs landed.

  • RDF (radio direction finding) matured rapidly from Watson-Watt's tests to operational Chain Home stations by 1937.
  • Multiple coastal masts and overlapping arcs enabled triangulation and early detection of incoming formations.
