10 years ago, nanotechnology governed by the breakthrough System HAYYIM was "installed" into the atmospheres immediately above Cairo, London, Hanover, Berlin, Los Angeles, New York, and Mexico City (you may recall that some commercial metropolises such as Sydney, Prague, Tokyo, and Paris refused the WNEO invitation, wishing their skies not be turned into "experiments"; Beijing also refused, claiming its scientists had developed their own restoration nano-programming).
Six months ago, citizens of the residential districts surrounding Hanover reported glints of sunlight and even some specs of blue above just around noon. Today, similar reports out of New York are popping up on the Network. Although it seems the "blue" is described as very pale, almost gray.
Though the three individuals comprising System HAYYIM's development team have all since passed on, I'm sure they'd be quite proud today. Especially considering the extreme hostility they were met with, both from the public and national governments. As well as the usual criticism from the Holy State.
Experts say it will be another decade on average before the skies above these CMs will be fully restored. Meanwhile, the rest of us in the Outer Residential Sector are enjoying our cloudy-but-relatively-clean skies. One of the few great things about being a middle-class commoner, I say.
