There were a few nearly identical incidents. Another involved someone working alone after hours dropping the last block of plutonium/uranium onto a stack during criticality testing after realizing that it was going to go critical, and removing it by hand.
Its pretty amazing that the test procedure for determining the critical mass was essentially "stack these blocks of plutonium/uranium (by hand) until the neutron detector starts going off, and then take one away"

Another involved someone working alone after hours dropping the last block of plutonium/uranium onto a stack during criticality testing after realizing that it was going to go critical, and removing it by hand. IIRC, that incident happened with the same sphere of plutonium, causing it to be called the "Demon Core".
