Some 40 years ago i was growing up in Radlett Hertfordshire. During the summer hols we would often walk across the fields to what we called Handley page, but was infact Radlett aerodrome. Today most of it is an industrial site and some given over to housing. The old entrance to the aerodrome is still there, now its the entrance to the industrial estate. Not been there for some years now but i recall some of the taxi ways were still visible
