A friend was doing some research into instrument flying and needed to locate a key text on the subject. This article from a 1937 issue on Flight is heavily cited in academic texts, but as of several years ago is not available online because the parent organization’s archive went dark during a site upgrade in 2019 and hasn’t reemerged. London-based Flight International has also been through an acquisition (DVV Media Group out of Germany) so finding the right person to talk to was tricky.
Because it’s so difficult to find this text and it seems to be so widely cited, I wanted to publish it here to make sure that other folks would have an easier time locating the text.
