I asked the question Who must approve a globally distributed satellite to ground laser communication system? a while ago in aviation statckexchange, and it met some resistance, but ultimately no answer despite a bounty.
I'm wondering if I should ask a similar question in SXSE. It's past the deadline to migrate.
It would of course be much shorter. The question grew as I repeatedly had to add material to counter false claims in comments trying to close. I think it was just too non-standard for that SE at that time.
Here I'd just ask something like "Who must approve a world-wide network of ground-space-ground internet laser beams? How might they avoid skies full of airplanes?
Would this be a reasonable question to ask and not be considered cross-posting?
I might include additional examples of companies interested in optical communications, perhaps some that have been in the news more recently.
