howdy - please excuse any non-conformance to the rules
as this is my first posting here.

i was wondering about the development of the lead
computing optical sight used in air gunnery.  when
were these sights developed?  i often see pictures
of WWII aircraft (especially late Mustangs) with
a projection plate similar to the HUD glass used
today.  (earlier Mustangs had ring and bead sights.)

were these sights lead computing?  if so, what
drove the optics?

for today's gunnery sights, are the optics driven
with radar input?  or are all the sights of this
type driven by accelerometers and gyros?

thanks,

-- arthur
