Details:
Horus 25 was another flight test of Mark's uplink cutdown payload. A day of lovely conditions and great weather saw two cars head out - Terry, Mark & Alan in one car, followed by Grant in his car. Grant (as usual) did an excellent job of capturing the day's activities on film:
As per Horus 24, the uplink and flight termination work perfectly, giving us another excellent opportunity to observe the balloon's landing.
