Macquarie Island 1968: Balloon launch on a windy day
From an old slide. This was some years before ozone depletion was recognised, but scientists wanted more data on seasonal changes to temperatures in the high stratosphere. We had a supply of special high altitude balloons for launching on set dates, but on windy days it was a tricky process and required lots of coordination for two people to successfully get the balloon, radiosonde (temperature sender) and large radar target away.
