  EPISODE TITLE: Episode 77: Birds in a Truck ORIGINAL AIR DATE: 4/18/2007 SYNOPSIS: In "Birds in a Truck," Adam and Jamie tackle Sir Isaac Newton's founding principle of thermodynamics and the law of conservation of momentum. They're looking into a physics' classroom urban myth. If birds in a truck take flight do they lighten the load? Watch to see if the 'Busters will be outsmarted by a flock of pigeons ... Meanwhile, Grant, Tory and Kari become crime scene investigators. A photo found on the Net shows a speedboat impaled on a channel marker, almost neatly split in half. In an effort to get to the bottom of this watery fender bender, our intrepid CSI team goes on a high-speed joyride. | |

To me the explanation is wrong, because the birds, planes, or a chopper does not fly because the air that pushes down. A wing and or a rotating wing produce lift by superficial tension (pressure does nothing and action/reaction pushing the air down is insignificant).
An airplane or helicopter passing over you does not apply pressure or weight over you. What happens if the birds are in an cage. Is easy to make a test with a box without front and rear panel in a wind tunnel, a model plane flying inside will not increase the weight of the box if it fly at a enough distance from the floor to avoid ground effect (an effect that help to support the planes during take off or landings at a distance less than one wing span from the ground). The air moving horizontally should not make any change in the weight of the box (open Truck). |

I'm still not convinced that this myth is busted. If you placed a bunch of birds in a cage on the bed of a truck and proceed to lift the birds within the cage off of the truck's bed, would it not weigh less (minus the cage of course)? What is the difference if the birds are flying about within the truck or if they are merely suspended above the truck's bed. The same could be said for passengers in a jet that is dropping at such a rate that they are temporarily suspended (weightless). Please enlighten me if I am wrong about this.
