Narrator: Sensors received a final check using a hydrogen light source rich in ultraviolet. The space between was flushed with nitrogen gas to prevent oxygen absorption. The radar transponder received a final check. Finally, the covers were fitted, the nose-cone was screwed down and WRESAT was ready. It was then taken to the launching area for mating to the rocket.
Here, with great care, to the relief of some and the confusion of the sceptics, it mated up perfectly and the whole assembly was ready for launching.
Erection was completed, the umbilical cord was attached. Through this cord, monitoring functions were maintained and power was supplied to ignite the rocket engines. In the nearby control van, missile functions were checked. When all was well the countdown began.
The optical tracker had a hazy view of the launcher scene due to the high ground temperature. As the countdown proceeds the heater–cooler drop tank is shed.
