Lyndon Johnson: “I cannot promise you that it will come this year--or come next year.”

This program, sponsored by the World Meteorological Organization, constitutes one of the largest and most complex scientific and technological undertakings ever attempted as an international effort.

I believe deeply in your cause and I believe in you.

Sometimes it is your job to go out and scout the road, to encounter and overcome the difficulties that always accompany such a vast new venture as this.

In that pursuit, Mr. President, United States support will be gladly given.
