Really stupid question about either physics, math or philosophy...

I have a comment about them pigeons. Is this the place to post it?

Jetliners do have a big open window during flight. The cabin is pressurized but not airtight. So I guess flying pigeons would decrease the weight of the plane.

Will this reach the almighty ears, or do I need to post this elsewhere?

It should go in “Comments” forum.

Basically the pack can not be held twice. It should not be counted twice. One pack, held by one person, only counts as one.

Situation: I have a 20 pound toddler. She has a 2 pound backpack. If she wears the backpack, she’s bearing a load of 2 pounds, right? If I then pick her up, I’m bearing 22 pounds (20 pound kidlet + 2 pound backpack), so altogether we’re carrying 24 pounds. But, of course, we aren’t. So “where” did the “extra” 2 pounds come from,

It did NOT come from anywhere nor somewhere!
