Once the dust settles, the data and more so, political and populus consensus will be more pro good air quality than currently and the momentum will see much change. That's my prediction of how this will traction over the years ahead.

Certainly see airplane tickets become more expensive as the days of cheap subsidized (low fuel tax's/duty) flights are in the end of days. Airlines running on razor thin margins will not survive this and personally, that's a good thing given the that IMHO the overall impact is a false-economy upon the environment.

Though that will only see more investment into electric planes, which will have a fair chance with a fair market for such competition.

Interesting times ahead, kinda focusing on the positives over the loss of life that will drive such change.
