You can't use a compass near the magnetic poles, because the magnet field lines go INTO the ground there, so Admiral Byrd used a sun compass, details here:

(From National Graphic, when it was actually informative, and not entertainment at the grocery check out line)

Trump needs to MNGGA!

Likewise with Sci Amer. Down with woke; it's a bloody joke. MA-woke free-A.

Answer me this one: Do all birds fly?

The Kiwi is a flightless bird with hairy feathers.

Dodos couldn't fly wither, but they are extinct.

The oldest fossil feathers have their quill down the center, and are not really useable for lift, by the way. They were insulation, we think.

But no human has a time machine, so we don't know for sure in this life.

How about penguins? They are birds, aren't they. They can't fly as far as I now.

Penguin wings are actually hydrofoils & penguins get propulsion from them, maybe you could call it flying, but it is in the water, not the air. So penguins don't fly either, in the usual sense of flying.

Some penguin info here:

And, why don't birds have vertical tails? Hint: They don't need them ! HERE is a brilliant video about that, and note the contribution of brilliant young engineers, the kind that are working for Musk right now, analyzing gov't waste, and roundly vilified by the Democrats for that.

Why birds don't have vertical tails: Brilliant video !

Watch one fly: Student engineers. New stuff. Problem solving. Enjoy ! No vertical tail. Complete control.
