52:33Walter AndrusGUEST
Uh, Project Sign was, was set up about 1947 after the Ken Arnold sighting and the crash at Roswell.

Now, if this is an area you're curious about, I want you to drop more theories in the comments because I want to learn more about this as well.

So the first official government-funded study of UFOs was called the USAF Project Sign in 1947 to 1948.
K

It was initially coded as Project Saucer.
K
35:47KylieHOST
The Air Force reorganized this project in late 1948 and named it Project Grudge in 1949 and transformed it later into Project Blue Book in 1952, which ran until 1969.
K

Project Blue Book was essentially utilized to create a methodical approach to the over 12,000 sightings and categorize them as identified or unidentified.

G
84:53George KnappGUEST
in essence, and everyone associated with it, including its first director, said that it was little more than a public relations exercise aimed at dismissing or explaining away UFO sightings.
G
85:04George KnappGUEST
Projects, which preceded Blue Book, Project Sign and Project Grudge, were a little bit different.
G
85:08George KnappGUEST
Project Sign was conducted in total secrecy.
G
85:11George KnappGUEST
It concluded that UFOs were real and probably extraterrestrial.
G

And then the next day it was like, no, no, no, it was a weather balloon, which that really is when what we would call the relative cover-up began.
M
16:47Mondo GonzalesGUEST
You have Project Sign, you have Project Blue Book, other... investigative reports it's interesting to me that it's like i liken it to there was an incident at the hen house where some potential chickens got taken but we hired the fox to investigate Good luck with that, right? I'm sure we'll get a truthful report on how that happened.
M
17:12Mondo GonzalesGUEST
I do recommend, if you want to get into some of the disclosure, the runs, L.A. Marzulli wrote a book recently, which is actually pretty good, where he systematically goes through all the different developments over the past few years, primarily beginning in 2017, which we'll see.

After they had written Project Sign, it was Project Sign which is the pre-runner, uh, forerunner to Project Blue Book.
K
