I took an old boy, my 85 year old neighbour Alf, for a local. We lifted from the field adjoining his property and went over the old Hatfield Aerodrome where DeHavilland used to make planes. He told me he was a cabinetmaker and used to work there making aero engines out of timber! He also made Concorde parts from wood as a pattern maker, later they were formed from aluminium by aero workers. He also went for a trial lesson in a Cessna from RAF Henlow nearby when he was 80.
