StratoCatLaunch of a cosmic ray experiment on July 21, 1969 from the #soccer field of the #River Plate stadium, in Buenos Aires, Argentina.
The stadium stands served as a virtual #windbreak to allow the balloon to be safely inflated & launched. Several balloon missions were performed there in 1969/70 by the Centro Nacional de Radiación Cósmica (CNRC) and the institution that succeeded it the Instituto de #Astronomia y #Fisica del Espacio (IAFE)
