If you have a read through Hawker Aircraft by Putnam it claims that the design had some roots in the Fury design, it also states “the aircraft combined the well-proven tubular metal cross-braced fabric covered Warren fuselage”, if you dug deep enough into the drawing system for the Harrier you will find parts that were used on Hunters, in fact there is a sringer section from Hurricane.

The design was right at the time, just the same as the Hunter, Harrier and Hawk designs where right at the time, I’ve worked with and in fact still do designers who started out on the Hunter then moved onto the Harrier and then Hawk, thus design methods and techniques do end up being used on the different aircraft.

I’ve also seen designs on the same aircraft that vary depending on where the designers where based, ie Warton, Brough and Kingston, all had there differnt construction methods, even in Germany parts of the Tyhoon designed by MBB in Munich differed to these designed in north germany.
