re: #432 Decatur Deb

Got its name from the organization that ran it—the Manhattan District of the Army Corps of Engineers. The boss was a one-star named Groves, a very effective SOB who earlier had brought the Pentagon construction in on-time, on-budget. AFAIK, there still is a Manhattan District—some of my buddies worked there on ordinary Engineer Things.

And you probably have to bet that Groves could herd cats. Imagine having to handle a huge pile of physicists and engineers like that for a project that massive and expensive.
