The Spirit of Dr A P J Abdul Kalam : “All Birds find shelter during a rain. But Eagle avoids rain by flying above the Clouds. Problems are common, but attitude makes the difference!!!”

“All Birds find shelter during a rain.
But Eagle avoids rain by flying above
the Clouds.

Problems are common, but attitude
makes the difference!!!” 

              ― A.P.J. Abdul Kalam

Kalam was invited by Raja Ramanna to witness the country's first nuclear test Smiling Buddha as the representative of TBRL, even though he had not participated in the development, test site preparation and weapon designing. In the 1970s, a landmark was achieved by ISRO when the locally built Rohini-1 was launched into space, using the SLV rocket.

 In the 1970s, Kalam also directed two projects, namely, Project Devil and Project Valiant , which sought to develop ballistic missiles from the technology of the successful SLV programme.
