Prof. Sarabhai was an exemplar in the art of team-
building. On one occasion, he had to identify a person who
could be given the responsibility for developing a
telecommand system for the SLV. Two men were
competent to carry out this task—one was the seasoned
and sophisticated UR Rao and the other was a relatively
unknown experimenter, G Madhavan Nair. Although I was
deeply impressed by Madhavan Nair’s dedication and
abilities, I did not rate his chances as very good. During
one of Prof. Sarabhai’s routine visits, Madhavan Nair boldly
demonstrated his improvised but highly reliable
telecommand system. Prof. Sarabhai did not take much
time to back the young experimenter in preference to an
established expert. Madhavan Nair not only lived up to the
expectations of his leader but even went beyond them. He
was to later become the project director of the Polar
Satellite Launch Vehicle (PSLV).
SLVs and missiles can be called first cousins: they are
different in concept and purpose, but come from the same
bloodline of rocketry. A massive missile development
project had been taken up by DRDO at the Defence
Research & Development Laboratory (DRDL), Hyderabad.
As the pace of this surface-to-air missile development
project increased, the frequency of the Missile Panel
meetings and my interaction with Gp Capt Narayanan also
increased.
In 1968, Prof. Sarabhai came to Thumba on one of his
routine visits. He was shown the operation of the nose-cone
jettisoning mechanism. As always, we were all anxious to
share the results of our work with Prof. Sarabhai. We
requested Prof. Sarabhai to formally activate the pyro
system through a timer circuit. Prof. Sarabhai smiled, and
pressed the button. To our horror, nothing happened. We
were dumbstruck. I looked at Pramod Kale, who had
designed and integrated the timer circuit. In a flash each of
us mentally went through an anlysis of the failure. We
requested Prof. Sarabhai to wait for a few minutes, then we
detached the timer device, giving direct connection to the
pyros. Prof. Sarabhai pressed the button again. The pyros
were fired and the nose cone was jettisoned. Prof.
Sarabhai congratulated Kale and me; but his expression
suggested that his thoughts were elsewhere. We could not
guess what was on his mind. The suspense did not last for
long and I got a call from Prof. Sarabhai’s secretary to meet
him after dinner for an important discussion.
Prof. Sarabhai was staying at the Kovalam Palace
Hotel, his usual home whenever he was in Trivandrum. I
was slightly perplexed by the summons. Prof. Sarabhai
greeted me with his customary warmth. He talked of the
rocket launching station, envisaging facilities like launch
pads, block houses, radar, telemetry and so on—things
which are taken for granted in Indian space research today.
Then he brought up the incident that had occurred that
morning. This was exactly what I had feared. My
apprehension of a reproach from my leader, however, was
unfounded. Prof. Sarabhai did not conclude that the failure
of the pyro timer circuit was the outcome of insufficient
knowledge and lack of skill on the part of his people or of
faulty understanding at the direction stage. He asked me
instead, if we were unenthused by a job that did not pose
sufficient challenge. He also asked me to consider if my
work was possibly being affected by any problem of which I
was hitherto unaware. He finally put his finger on the key
issue. We lacked a single roof to carry out system
integration of all our rocket stages and rocket systems.
