Balloon launch, likely on Ascension Island. 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 vehicle to travel in the opposite direction of the wind at the prevailing speed of the wind to create a "zero wind" launch. This vehicle is probably from the 1980s; earlier launch vehicles were dubbed "GHOST wagons" and were towed by a standard pickup truck.
