It is now 72 years since the Wright
Brothers made the first controlled flights with a
manned heavier-than-air machine, and I am deeply
conscious of the great honour conveyed by the
invitation to deliver this 64th Memorial Lecture
commemorating their great achievement.
Their research and development work
provides a classic model of a combination of the
scientific and practical approaches to the
solution of a major problem. However, it is
fascinating to look back to those very different
days at the turn of the century, and see how
incompletely they foresaw all the consequences of
their own efforts. Contemporary evidence suggests
that their vision was confined to certain
secondary uses of the aeroplane, such as military
reconnaissance, sport and exploration.
