While silverstrata's post is hardly relevant to the topic thread, his sentiments are a consequence of market economics. However, it is not clear if he has decided to become a dustman in preference to a pilot. If the job satisfaction of the former is as good as the latter, I'm sure he would have done it by now.
Nobody in this thread seems to be mentioning how to get to this island in the Thames (well actually, they might have done, but I've just realised I'd have to review 64 pages to confirm this). It would cost a fortune to build a new rail and road connection - and don't say 'extend Crossrail' as that will already be rammed with commuters, including those who have lost jobs at LHR, and can't afford to move to the new airport.
