Judging by the radical thread drift in the Manchester discussion, perhaps its time to air the subject separately so as not to pee off readers and contributors who's interest doesn't extend to the issue.
First off, commercial aviation isn't going to cease - fact. Second, climate change is real, happening now, and since the dawn of the industrial era at a much faster rate than through previous centuries - also a fact.
How do the stakeholders in the industry (airlines and airports) balance the need for change to reduce emmissions without resorting to
PR 'greenwash' that only the gullible fall for with maintaining their businesses and viability? Perhaps its a circle that can't be squared, but I actually doubt that.
Perhaps from an airport standpoint more renewable power generation, reduce heating and lighting in terminals. Perhaps better public transport for staff and PAX.
Perhaps from an airline standpoint an end to slot sitting schedules at major airports, perhaps more direct routings developed through technological advances in air traffic management.
Thats an opening gambit. Perhaps MAN can get its thread back!
