Limits of the Flying Machine.
In the opinion of competent experts it is idle to look for a
commercial future for the flying machine. There is, and always will be,
a limit to its carrying capacity which will prohibit its employment for
passenger or freight purposes in a wholesale or general way. There are
some, of course, who will argue that because a machine will carry two
people another may be constructed that will carry a dozen, but those who
make this contention do not understand the theory of weight sustentation
in the air; or that the greater the load the greater must be the lifting
power (motors and plane surface), and that there is a limit to these—as
will be explained later on—beyond which the aviator cannot go.
