Interesting drawings - reminded me of Cordwainer Smith's Earthport.
See eg http://www.fourth-millennium.net/ (a site to spend several hours at, if you're
a Smith fan).

My real comment was that half (from casual visual inspection) of the skyscrapers in present-day
Tokyo have helipads on them, and they are basically built directly on top of the buildings or
projecting from the roofs - no big separate towers. IIRC helipads were/are encouraged/mandated by
the building codes, for the use of emergency services for building evacuations. Most of them have
never been used for anything. Yet.

Apparently Los Angeles used to have a similar requirement, but dropped it in 2014. There's
a helipad on top of the Burj Al Arab hotel.

Certainly once you get to grav vehicle tech (dragging this back to Traveller), you could easily
have the executive entrance to your office building on the 99th floor, or whatever. Grav vehicles
(at least IMTU, yours may vary, and it may make for a decent discussion) have no dangerous whirly
things on them, and no nasty exhaust fumes, so there's no obvious reason to keep them separated
from people walking around.
