Nice post.

I didn't know Pigeon was in MB.

I saw this the other night, what a huge waste of time. No, even birds cannot defeat elementary laws of physics.

In an enclosed trailer like they one they use, this is true. If, however, you were carrying the pigeons in an OPEN AIR trailer (say, one that was enclosed with chicken wire), then the air beating down from their wings can escape the trailer and actually "lighten" the load while they are in flight.

MycroftHomlz, thanks - knew I was forgetting something!

Haricot: You've completly ignored the fact that it isn't the weight of the air but rather the force it exerts on the floor. In order for something to fly it must exert a force at least equal to its mass in order to oppose gravity. The air will always have to hit the floor of the truck before it escapes out of the sides even in your chicken wire container, and that is when the force is exerted.

I am well aware that the force of the air being exerted downwards by flapping wings is why the weight of an ENCLOSED trailer stays the same. Read my post carefully, I never said the bottom was solid. Here, I'll be explicit: If the truck's trailer was just two axles with a giant cage (with no floor/bottom tray) then yes, the truck will be "lighter," since the air being forced downwards will pass through the wires of the cage bottom and be exerted on the road, and not the trailer.

Sure, some infinitesimal/negligible amount of the force will be applied to the cage wires themselves, but the vast majority of it will pass right through.
