Slightly off key, but to do with weather forecasting.
In 1958 I was at RAF Gan and we had a couple of weather assistants. One of their daily tasks was to inflate a weather balloon, launch it as shown below, take the readings (angles) with a theodolite and pass the details back to RAF Negombo (Katunayake) for their forecaster to include the wind directions and speed at different heights in their forecasts.
Passed on FWIW
