Re: four winged Archaeopteryx
Note that I have no objection to mobile aerodynamic feathers and realize that
many
are, but by analogy, does the statement below mean that proposing immobile
fixed wings
for aircraft would be a very strong claim? I note in passing, that immobile
fixed
wings are not unusual in aircraft, and that they are expected to work for
flight.
