I visited the former Walmer airfield nearly three years ago (see near the foot of this page
http://inreachoftheskies.co.uk/airfields%205.html) to find that nothing really remains from its flying days, unsurprising since it closed in 1919. However, in May next year as part of a Vintage Air Rally the last airworthy Airco DH.9, flying from Belgium, will land at Walmer, the first aircraft to do so in 99 years. The last aircraft out of Walmer was also a DH.9!
I'll have to keep tabs on this
