While pterosaurs, the flying reptiles that lived during the Age of Dinosaurs, were not dinosaurs, paleontologists now classify modern birds as dinosaurs. There was also the relatively recent discovery of microraptor, a small feathered relative of velociraptor that may have had a limited flight capability.
Most did not. There were only very few like the pterodactyl capable of flight
Pterodactylus and other flying reptiles, collectively known as pterosaurs, do not belong to the clade Dinosauria, and thus aren't dinosaurs. This is because they did not evolve from the common ancestor of all dinosaurs. All dinosaurs were terrestrial animals, and with the exception of birds, they couldn't fly. All pterosaurs were winged quadrupeds, and at least most of them were capable of flight.

Tyrannosaurus belonged to the clade Coeluosauria. Coelurosauria includes birds, maniraptorans, and Tyrannosaurs. However, birds did not descend from Tyrannosaurus or any of its immediate relatives.
Bats are the only mammals capable of true flight. Their wings are like hands with skin stretched between modified finger bones.Bats and most birds a capable of sustained flight, and they are vertebrates

Aeronautics (Greek, meaning, "air navigation") is the science involved with the study, design, and manufacturing of flight-capable machines, or the techniques of operating flight-capable machines.
