Over a year ago John Clifford and I exchanged information on Harpsfield Hall, near Hatfield, which was demolished when Hatfield Aerodrome was constructed in the 1930s. John's research is progressing and on June 24th he is giving a talk entitled de Havilland in Hatfield - The Golden Years on June 24th at County Hall, Hertford. [Details].
