Really old biplanes

The first flying dinosaurs took to the air in a similar way to a World War I bi-plane, a study shows.

A fresh analysis of an early feathered fossil dinosaur suggests that it dropped its hind legs below its body, adopting a bi-plane-like form.

This contrasts with earlier reconstructions showing the dinosaur maintaining its wings in a tandem pattern, a bit like a dragonfly.
