I want to know the answer to the following question:
On what day was the first atomic blast?
All the background I'm provided with is that "On July 16, 1945, with numerous other Manhattan Project personnel, von Neumann was an eyewitness to the first atomic bomb blast, code named Trinity, conducted as a test of the implosion method device, at the bombing range near Alamogordo Army Airfield, 35 miles (56 km) southeast of Socorro, New Mexico.". Is that enough to answer the question?
Answer: yes
