If The U.S. Air Force Stopped Investigating UFOs in 1969, Then, What The Heck Is This...?

From 1947 until 1969, the United States Air Force was involved in the investigation of Unidentified Flying Objects (UFOs) under Project Blue Book (Initially called Project Sign, then Project Grudge).  Blue Book was headquartered at Wright-Patterson Air Force Base in Ohio.  It was terminated on December 17, 1969.  Out of 12,618 sightings reported to Project Blue Book a total of 701 cases remained "unidentified".

The conclusions of Project Blue Book are as follows: "(1) no UFO reported, investigated, and evaluated by the Air Force has ever given any indication of threat to our national security; (2) there has been no evidence submitted to or discovered by the Air Force that sightings categorized as "unidentified" represent technological developments or principles beyond the range of present-day scientific knowledge; and (3) there has been no evidence indicating that sightings categorized as "unidentified" are extraterrestrial vehicles."

The Air Force's statement goes on to say: "Since Project BLUE BOOK was closed, nothing has happened to indicate that the Air Force ought to resume investigating UFOS."

If the above official Air Force Statement is true, then...
Why did the following excerpt from Air Force Instruction 10-206 include instructions on how to report an unidentified flying object?

And, then... why did this entire section of Air Force Instruction 10-206 disappear from the Instruction Manual after The Huffington Post made an inquiry to the Air Force as to what these specific instructions meant?

Curiouser and curiouser...

SUBMIT REPORT WHEN (DESCRIPTION):
Any/all unidentifiable,
suspicious, or hostile
traffic (land,
aerospace, or sea)
which, because of its
nature, course, or
actions, may constitute
a threat to the security
of the US or Canada.
Includes reports
received from airborne
platforms.

5.6.3. Report the following specific sightings:
5.6.3.1. Hostile or unidentified aircraft, which appears directed against the United States,
Canada, or their forces.
5.6.3.2. Missiles.
5.6.3.3. Unidentified flying objects.
5.6.3.4. Hostile or unidentified military surface vessels or submarines.
5.6.3.5. Any other individual surface vessels, submarines, or aircraft of unconventional design
engaged in suspicious activity, observed in an unusual location, or on a course, which may
threaten the United States, Canada, or their forces.
5.6.3.6. Any unexplained or unusual activity, which may indicate a possible attack against or
through Canada or the United States (includes the presence of any unidentified or suspicious
ground parties in remote or sparsely populated areas, including the polar region).
5.6.3.7. Unlisted airfields, facilities, weather stations, or air navigation aids.
5.6.4. Make every effort to document sightings with as many photographs as possible. Send undeveloped film or prints and negatives, with a brief written report and other identifying information to the Director of Naval Intelligence, Department of the Navy, Washington, DC 20305. The Department of the Navy will process the film and return one copy of each print and a roll of new film to the individual. 
5.6.5. Use Figure 5.1. to gather and report specific sighting details.

GUIDE FOR CIRVIS REPORTING
The CIRVIS report is a narrative report explaining the sighting. A specific format is not required.  Provide as much specific detail as possible to aid decision makers in responding to the sighting.  Include the following information, if possible, along with any other information, which may be significant:
1. CIRVIS report identification.
2. Identification of the object sighted.
a. For identifiable objects, include number and identification of the aircraft, vessel, missile, or
individuals seen.
b. For unidentifiable objects, give a description including shape, size (compared to a known object e.g., pea, silver dollar, baseball, basketball, fighter aircraft, or C-5), number and formation, any discernible features or details (e.g., color, trail or exhaust, sound).
c. Include any observed identification (e.g., insignia, lettering, flags).
3. The position of the object. Include the date and time (GMT) of the sighting. This can be indicated by any of the following methods:
a. Latitude and longitude.
b. Over a radio fix.
c. True bearing and distance from a radio fix.
d. Over a well-known or well-defined geographic point.
4. Description of the course of the object:
a. Altitude.
b. Direction of travel.
c. Speed.
d. Description of flight path and maneuvers.
e. What first called attention to the object?
f. Angle or elevation and azimuth when first observed.
g. How long was the object visible?
h. Angle or elevation and azimuth upon disappearance.
i. How did the object disappear?
5. Manner of observation.
a. State how observed: ground-visual, ground-electronic, air-visual, and air-electronic. (If electronic, specify system).
b. Were optical aids (telescope, binoculars, etc.) used?
6. Conditions when sighting the object.
a. Location of observer. (Use latitude/longitude, a named geographic landmark, or other logical references.) If the sighting is made while airborne, include type of aircraft, identification number, altitude, heading, speed, and home station.
b. Light conditions (use one of the following terms: night, day, dawn, dusk).
c. Weather conditions (ceiling, visibility, clouds, thunderstorms, temperature, winds, etc.).
7. Interception or identification actions taken (if feasible, complying with existing directives).
8. Location, approximate altitude, and general direction of flight of any air traffic or balloon releases in the area, which could possibly account for the sighting.
9. Preliminary analysis of the possible cause of the sightings.
10. Existence of physical evidence, such as materials and photographs.
11. Name, organization, and means of contacting the reporting individual.
