Steel Test Cylinder and Tower Sketch, July 18, 1945
The sketch is of a test cylinder procured and installed at a time when we were uncertain as to the explosive power of the bomb. If, at the time of the test, we anticipated that the force might be relatively small or even that there might be no nuclear explosion, we were going to place the bomb in the cylinder so that it would be possible to recover the plutonium.
