I'm still skeptical. 

I could see that it might be a problem with the larger AA guns that
used mechanical computers to calculate the aiming point.

Small-calibre guns had fairly simple "spider-web" sights. These could
be aimed straight at a slow-flying plane and the aim could be corrected
by watching the tracers.

Do you consider your book a well-researched technical work, or more of
the popular kind ? Does it quote sources ? Not everything you see in
print is neccesarily accurate :-(
