> Helipads are cheaper to build and site than train stations

Is that still true once you control for capacity? A modern single-line station is handling, what, 150 people alighting every 2.5 minutes? How many helipads would you need to match that?

> $200 a trip. Assuming that's only affordable for someone making $50k a year or more, that covers the top 80% of Manhattan

Someone making $50k isn't going to spend $200/trip regularly. They might spend it occasionally for an urgent trip, but how often is that going to be to/from an airport? For someone making $50k any flights they're taking will have been planned and booked months in advance, they can't afford to fly spontaneously/last-minute. (And if 80% of the population did want to use it, would it even be possible to build enough enough helipads? There isn't room for anything like 80% of the population to park in Manhattan, and these things look to be bigger than cars and I don't see anyone putting them in a multi-storey garage).

They don’t fly regularly. I picked that number because it puts $200 into the reasonable splurge bucket, and that’s the lowest income of a friend I know who has taken one more than once.

If $50k doesn’t do it, take it to $80k and still understand that covers quite a bit more than half of Manhattan. Plugging these services as top 0.1% is wrong—that’s private jets.
