He's touting the usual rubbish that improvements in technology will mean we can keep flying, but implies that even if they don't, we'll have to keep flying anyway because aviation is "a source of social and economic advancement, equality and great pleasure for the many people who are transported to the corners of this beautiful planet". The guy's claiming that aviation is a source of EQUALITY!!! Tell that to Bangladesh you moron.
Please put him strait on a few points, by emailing him at firstname.lastname@example.org
