Macquarie Island 1968: Away she goes!
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.
