Balloon launch on Ascension Island in 1970. The winds were so constant on Ascension Island in the late 1960s that the Global Atmospheric Measurements Program (GAMP) Group, headed by Vincent E. Lally, devised a wagon pulled by a truck traveling in the opposite direction of the wind at the prevailing speed of the wind to create a "zero wind" launch. The GAMP group was launching superpressure balloons to test the feasibility of creating a GHOST(Global Horizontal Sounding Technique)network of balloons gathering atmospheric data to improve basic meteorological understanding and improve weather forecasting.
