The memorandum indicated that a "sub rosa" group - government instigated? - was engaged in a large-scale analysis of UFOs well before the Robertson Panel, which the "secret group" wanted cancelled or postponed.
The Robertson Panel was unaware, apparently, of the secret group's" work.
Ritchie writes that "The memo also referred to a mysterious 'Project Stork.'"
Internet links (via Google) about Project Stork include these:

And another from Philip Coppens:

In what little material and notes from Stork provides resides references that will help UFO buffs with Roswell and early UFO/flying disc events.
And that secret pre-Robertson Panel group was what MJ-12 was all about, except that MJ-12 was a bogus configuration, hoping to point UFO researchers to the early secret analytical group but ineffective as UFO aficionados didn't get the hint or purpose and got sidetracked by a desire to prove MJ-12 fraudulent, which it was, but it's intent was otherwise.
