Where does a snarky Valkyrie get a drink around this joint?

Q: how, the hell, do you get air to flow through a flute??
In school I was a trumpet player who wanted to be a flute player! Then I got a flute for Christmas and truly really tried to no avail for, years.

Short answer:  It doesn't go through the flute; it goes across the hole in the mouthpiece, much the same way as you get a tone when you blow across the top of a bottle.  Ideally you want to keep your lips very close together and send a hard, thin, fast stream of air across the hole.  You may have to play a bit with the angle to get a nice tone.  The second octave is actually easier to play than the very low notes, by the way.

Here's a chap who can demonstrate it very well:

Flute also doesn't have the same high back pressure that a trumpet has, so there's a lot of wasted air.  At least at first you may have to take more frequent breaths, perhaps being able to play for 2 bars when everyone else can play for 4 before taking a breath.

Also can you translate Flugstad?

I think it means "Airport" in German.
