You want to put a delicate-cable factory on an airplane and figure out how to shape all materials from start to finish in 30-second bursts while also compensating for turbulence, additional Gs on ascend, flight adjustments, and proper stowing for takeoff and landing? ... Oddly, that's the more practical of those suggestions, because forming a few kilometers of perfect glass by letting it cool while dropping would seem to require a tower impressive in its own right... More relevant, there are QA demands with fiber-optics that don't seem to jive with a "let it hit the ground and throw out the lumpy ones" approach, much less the handling while in full gravity (which is where the issues are).
