Even 32 kilometers (20 miles) away, observers felt the heat of the explosion on exposed skin. The radiation level in the rising mushroom cloud was so intense that it emitted a blue glow.
Enrico Fermi dropped pieces of paper to estimate the force of the blast. Luis Alvarez, flying in an observation plane, made sketches of the cloud. Cyril Smith came to “the realization that a city is henceforth not the place in which to live.”
