[We] have lots of places these can be “launched” from around the globe (even Antarctica, just sayin) as well as airborne launchers.
Again, they may be “proof of concept” objects only; the wright brothers started out with a skeleton of basswood.
Today, we fly metallic apartment complexes.
I will stress this is just my fevered mind.
Quick thought on that last post regarding Antarctica.
Would make sense to launch from a pole of the magnetosphere if it were designed to “ride” on the gauss of Earth’s magnetic field.
