Swifts and Jet Fighters

Excerpt from Creation - Vol. 29 N o. 1 'The Design of Swifts and Jet Fighters' by Dr Jonathan Sarfati.

Bird aerobatics have fascinated bird watchers since the beginning. Bird design has inspired the designers of flying machines for over a century. Yet still there are new discoveries about their intricate engineering, suggesting that we still have much to learn.

God revealed that He created flying creatures on Day 5 of Creation week, the day before He created land creatures and man. However, progressive creationists deny this and believe that land reptiles came before birds, and evolutionists believe that birds evolved from reptiles.

Evolution-promoters seem not to understand how flight works, and how it needs so many things arranged in the right order....... Skeptics also ignore the amazing feather. The feather is an aerodynamic marvel that's strong and lightweight, and completely different from a reptile scale. But feathers are not the sorts of structures that would be useful on limbs that flap at a prey animal, since they would be damaged by the pounding.

The purpose of the wings is to force air backwards and downwards so the bird is propelled forwards and kept aloft. So wings should form a wide surface that has high air resistance, so it can move large volumes of air. But for limbs designed to grab forward at prey, it's an advantage to have a surface that has low air resistance i.e. lets air through easily.

A recent study on swifts shows that there is even more to flight than downward deflection of air. They also make use of a leading-edge vortex to generate even more lift, so that 'the current understanding of how birds fly must be revised'. The bird wing actually has two parts: the inner arm wing and an outer hand wing. The arm wing deflects air downwards just like an airplane wing.

This is a giant study and children would be itching to understand. Amazing how children mostly try to fly like superman by jumping off fences or whatever.
