"Aerodynamics for Naval Aviators"
 

Still the best manual for handling qualities testing, in my view.

twochai,
I've now seen that one cited so often, I'll go and order myself a copy.

It's still available, I've seen, both reprints and second-hand. And still affordable.

By chance I discovered “The lonely sky” (second hand paperback $4.95) and wish to endorse Pilot DAR’s recommendation (#2). The book provides an interesting insight to a self-taught test pilots involvement with early transonic / supersonic flight in the Douglas Skyrocket (D-558 1 / 2).
Bill Bridgeman’s autobiography deals with down to earth flight test issues as a project development tp, often from a very personal perspective. In parts it’s a sobering read, well worth seeking out both for prospective and existing tp’s. A good ‘prequel’ to Scott Crossfield’s “Always another dawn”.

The Lonely Sky by Bill Bridgeman & Jaqueline Hazard

"I Have Left the World" - TIME

I thought I already recommended that, but it may have been in another topic.

Anyway, I heartily second safetypee's endorsement.
