Fantastic Jonathan !! The description of the atmosphere is great, very nice style !!!!!
In the '50's we lived near Eelde where the Dutch flying school was stationed and we always had flying students around in our house as guests (via the fieldhockey they played together with my brother and sister). They just came by or stayed for days for studying. Untill my father asked them to stop it, we regularly had litlle airhows over our house by those guys with (indeed) Tiger Moth's and Harvards and during a holiday at Schiermonnikoog Island there was a dusk low level "bombing raid" with a Beech 18 with closet rolls (!) being thrown out of the passenger door..... Those were the days my friend......
The pilots ended as 747 captains with KLM - we are still in touch with them - so in the end all was well, but the beginning was like your story !!
I have a very nice book with paintings and drawings by Serge Stone about life in the KLu, which also starts out with Tigers and Harvards in the way you so vividly describe ..
Great Job !!
