As someone who has built airplane models since I was a kid (and still do when I can) I am always fascinated and intrigued by books on the early days of airplane technology.
The people who built and flew these early rickety and fragile machines were either incredibly courageous or incredibly foolhardy and insane… perhaps a combination of all three.
I’ve just added a few more books on building aeroplanes as they were called early on. These are specific books on the construction and design of aeroplanes that pretty much encompass everything that was known in the first decade or so of the 1900s.
I’ve updated the Category ZIP file and finally found the code that was excluding the .ZIP files. WHY I excluded them originally I have NO IDEA but it’s now fixed
