National Atomic Museum issued the following announcement on June 15.
June 15, 1966 | On this day in 1966, the United States conducted the Double Play underground nuclear test in a tunnel at Area 16 on the Nevada Test Site, now the Nevada National Security Site. Part of Operation Flintlock, Double Play was a weapons effects test and had an explosive yield of less than 20 kilotons, or less than twenty thousand tons of TNT.
Featured is a photograph of the certificate that test site workers would receive to certify that they participated in Double Play. We have many certificates just like this at the museum!
