For instance, flying demands amazingly complex and specialized structures and instinctual skills. Yet such diverse creatures as birds, bats and many insects all fly. Evolutionists have not been able to explain the evolution of flight or even guess how it could occur.
the most recent articles if one would not be very lazy and type in evolution of flight in a scientific search engine ( and i didn't even bother to do an intelligent search):

Wing upstroke and the evolution of flapping flight
Samuel O. Poore, A. Sánchez-Haiman, G. E. Goslow
SUMMARY: Movements of the wing during upstroke in birds capable of powered flight are more complex than those of downstroke. The m. supracoracoideus (SC) is...
CONTEXT: ...presence in recently described Late Jurassic or Early Cretaceous species. The evolution of this condition is thought to have been important for flapping powered flight in improving the function of wing elevation,, but the......

SUMMARY: The evolution of feathers and flight were generally thought to be inextricably linked. But new fossils from China show that feathers pre-dated the origin of...
CONTEXT: ...to dinosaurs. Feathers are the most distinctive attribute of living birds. Traditionally, their evolution has been linked to the origin of flight, but there have always been a few dissenting opinions. Two new studies, one published......

Molecular evidence regarding the origin of echolocation and flight in bats

CONTEXT: ...both groups have distributions that are restricted to the Old World. Our results have implications for the evolution of both flight and echolocation in bats. First, bats and flying lemurs did not share a flying common ancestor as......

oh yeah...i know that not everybody has access to scientific journals, but if you are interested in any article inspector feel free to ask me to send you it. It might be worth to educate you.
