From an old slide. This was taken just moments after my previous shot. As I commented, successfully launching the large balloon, radiosonde (the white box for sending temperatures) and large radar reflector (the funny mesh thing in the middle) was tricky on windy days such as this one: note the relative angles of the balloon, pulling hard, its payload, and the horizon.

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.
