ATLANTIC CITY, \. j., May 27.-l
Samuel d. Mott, a charter member OF
the Aero Club of America, who has just
completed a special study of aeronautics
with the view of future attainment, in
an address before the second Pan Ameri-l
can Aeronautic convention here said that
the future of commercial aviation depend
ed upon the ability of aviators to fly
above the storm limit. thus eliminating
weather from the aerial log.
I'VE have read Of many men larry

was glorious undertaking, our navy's ex-
| pedent was WISE and all honor to the |
| brave men attempting the test, but | sub
| NIT that waiting indefinitely for ideal
weather conditions for long distance fly
/ ing over land or sea win not do for the
demands of commerce. Therefore. by the
process of reasoning that Holland applied
| to boats to go out of sight beneath the
stilled waters of the ocean, | conceive
and would bring to your attention the
possibilities of the antithesis of the sub
marine, the altitude plane or altiplane,
as distinguished from the ,airplane or
| hydroplane, to 90 into the stiffness OF
nature above the weather
