On NASA Secrecy....
Go to ANY NASA webpage and look at the bottom...
There you will see in the fine print...
Freedom of Information Act
www.hq.nasa.gov...
On that page there is this statement...
"A link is also included to the NASA FOIA Regulations, "Availability of Agency Records to Members of the Public" which will provide you with more
detailed information concerning the processing of your FOIA request. "
"Availability of Agency Records to Members of the Public"
www.hq.nasa.gov...
Go down to "Subpart 3--Exemptions"
Under "Sec. 1206.300 Exemptions." you will see...
"(b) The requirements of this part to make Agency records available do not apply to matters that are--
(1)
(i) Specifically authorized under criteria established by an Executive Order to be kept secret in the interest of national defense or foreign policy
and
(ii) Are in fact properly classified pursuant to such Executive Order;"
So basically they don't have to tell us JACK if its under 'national defense or foreign policy" or just the whim of "Executive Order;".
I would assume that would include ANYTHING related to any Aliens
Now the really GOOD stuff at NASA is found here... but you have to know WHO to ask, and WHAT to ask... then explain WHY you need to know about that
and then they might give you access

(Like the file on Mars Methane)
