Just curious... is there some sort of a
G/S mini function on the
Bravo planes?
Anyway, if flying still is a way of making a structure big enough to contain boxes and accommodate some humans inside it, beat the earth's gravity through the air flow "sucking" phenomena provided by Mr. Bernoulli's principles, how it's done has changed radically throughout this past century: from the Wright bros simple machine with just a piece of string as their first and only flight instrument through the
Alpha aeroplanos. Sorry, but IMHO, A is leading technology wise.
From a Darwinian perspective, A and B evolutive ramifications are very much like the Humans and the Chimps, both Primates but with completely different technologies.
