Development
In 1921 the Engineering Division of the USAAS designed a simple single-seat biplane to be used as a messenger aircraft to replace motorcycles. The aircraft was built by the Sperry Aircraft Company as the Sperry Messenger. The Messenger was a conventional biplane with a fixed tailskid landing gear and a nose mounted 60 hp (45 kW) Lawrance L-4 radial engine. In 1924 the military aircraft were given USAAS designations M-1, M-1A and MAT. The prototype was used by Lawrence Sperry who disappeared in 1923 flying a Messenger across the English Channel from France to England.

Famous quotes containing the word development:
“Men are only as good as their technical development allows them to be.”
—George Orwell (1903–1950)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
—Women’s Liberation Workshop, Students for a Democratic Society, Radical political/social activist organization. “Liberation of Women,” in New Left Notes (July 10, 1967)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
