Document Summary

1 year = 24 million commercial flights: percentage of flights that actually had problems is very miniscule, the safest mode of transportation we have. First depiction of flight was made by da vinci (1452-1519: knew flight was possible, didn"t know mechanism behind it. Magnitude is proportional to the area of leading edge of projectile. Caused by a difference in pressure: higher pressure zone = leading side, lower pressure zone = trailing side of projectile. Make the leading edge of your body as small as possible. Caused by water moving past surface of body. Boundary layer of air sticks to projectile: laminar flow. Can see the boundary layer of fluid travelling very close to the body. Dependant on the surface texture of your skin; rough surface = more surface drag. Shark"s skin is composed of many tiny scale, creating an almost seamless skin. = keeps surface drag to a minimum = can move quickly through water.
