Glenn Martin predicted correctly
that the future of airframe manufacturing
lay in the new aluminum structures. Taking

to sell his old factory at a good price,
he built a new one designed from the first

Navy greeted Martin's new venture with a
lavish string of orders for flying boats
during the heady spring and summer of 1929.
The existing stock of World War I flying
boats was wearing out, just as Navy planners
were giving increasing emphasis to their
role in a possible confrontation with Japan
in the Pacific.
