Quick reply.  A "Veriport" is a thing/concept and highly debated if we 
need this term separate from the traditional "Aerodrome".

a Veriport is an aircraft launch/land site that ONLY supports vertical 
take offs and landings.

ASTM has a whole standard on how to design such a thing.  Many cities 
are looking on zoning rules as to where they will be allowed based on 
ASTM standard.

I can add this to the definition section?
