I agree; the one thing we really need is another heliport in the capital.
Not just one Shy, several!
In the same way that innovative helicopter designs can stimulate sectors of the market; well designed appropriately placed helicopter landing facilities can do the same .. if tied to creative efficiency-enhancing incentives which bring benefits to users and providers (clients and operators) alike. Helipads/ports are crucial in this equation and
can stimulate business and drive demand.
Modern cities served by multiple (usually [but not exclusively] roof top) helipads provide an indispensable advantage over those which do not and in a city such as London would be a godsend.
The opportunity is there for someone to push back against the tide of ineptness and dithering which has swept over the UK's rotary-wing industry with regard to city helicopter access. The BHA/B should have taken-up this fight long long ago .. and stuck with it until change was achieved!
