Development
The SM.78 first flew at the end of 1932, designed for the role of maritime reconnaissance-bomber. It was one of the many flying boats made by SIAI (Savoia-Marchetti), that in 1915 had started building foreign aircraft under licence, followed two years later by the first of its own designs.
The SM.78 was developed from the SM.62bis. The prototype, which carried the serial number MM222, made its first flight late in 1932 and then transferred the next year to Vigna di Valle for evaluation. The SM.78 was the last biplane flying boat, built or used in large numbers by Italy; 49 were completed in all (32 by Piaggio and 17 by SIAI).

Famous quotes containing the word development:
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
—Jean Baker Miller (20th century)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
