was the second Skylark launched. As with the first, the vehicle
carried no university experiments, only RAE
test instruments to monitor performance.
An improved Raven IIA motor was used.
Preparation: Wednesday 22nd May dawned fine with a moderate
breeze from the south. Final preparations started at 13:30, and firing
occurred at 14:50
Flight: This second
flight reached a height a height of 250,000 feet (47 miles / 76 km),
over six times as high as SL01. Unfortunately, because of an error in
setting the launch tower dial readings, the vehicle flew far to the right
of its intended path.
impact point was outside the range boundary, and "...wisely it was it was
decided not to go and look for [the Skylark] as that would have drawn
attention to it." Thus the impact could only be estimated as 111 miles
(179 km) downrange.
favourable position of the Sun meant that optical tracking was
considerably better than SL01. Telemetry and other records were
satisfactory. Useful heating measurements of the nose cone were again
obtained, although the vibration sensor amplifier failed in flight.
