Debris found in Southern CA Desert - Anyone know what it might be?

FYI, I did confirm today that the first item found:

http://home.earthlink.net/~jpa_2/wreckage_sm.jpg

was indeed an F-8's afterburner

Thanks again to all those who contributed their time....

Well so much for my hydraulic control surfaces actuators theory- that is
indeed the item based on the photo; now to figure out what caused it to
come free of the motor...did the aircraft suffer an afterburner
explosion? Did the turbine wheels disintegrate, and saw the tail off of
the plane (that's been known to happen).
Here's a cutaway of the motor:

Doesn't the F-8 have a J57?

Yes. But there isn't much difference between a J57 adn a J75, other
than the J75's much larger size.

An *inverted* one might have a J75.

Let me guess...I transposed the designation during my Google search,
didn't I? I'm really bating a thousand on this, aren't I? I say it's a
A-5 Vigilante wing- it's a F8 tail; I say that they are tail control
surface hydraulic actuators- they are afterburner nozzle actuators; I
say it's a J57- it's a J75; I say "tomato"......and it hits me right in
the face... :-[

Okay...rub it in, rub it in...when I seize complete power over the
universe, the first two things that get done by my "Special Executive
Branch For Historical Revision And Correction" are the changing of all
records so that the Juno II is revealed to be a obscure derivative of
the Thor missile; and the release of secret government records that show
that under the classified "Operation Kickass" program, all F8s were
upgraded to use J75 motors as soon as they were assigned to their
carriers....
Then of course their is that small matter of how your great-grandfather
was seen towing an iceberg out to sea...and into the path of the RMS
Titanic...while he was in the pay of the Compagnie Generale
Transatlantique! As to your mother being the one who introduced John
Lennon to Yoko Ono during a LSD-crazed "Free-Love" party in the
Maharishi's Leather Dungeon ...well...that story is well known already,
isn't it? :-)

I doesn't work that way. The only jet I know of where teh wing is a
single structure is the Folland Gnat (Little teeny fighter, with a
wing span smaller than most other fighter's stabilator spans) You
see, the problem comes when you've got to haul 'em around, or
disassemble them for maintenance, or other such stuff (such as
building them in the first place).

I know some more. The Harrier and the F-8 Crusader. Both neither
huge or little teeny fighters. They have to remove the wing from the
Harrier to change out the engine (which is why the Harrier I saw at
Boscombe Down in the mid-70's was in two pieces, the wing and the
rest).

Durn. Ya got me! In my haste, I forgot 'em.


Since they're so much like F-8s, the A-7 Corsair may have had a
unitary wing. I don't really know much about A-7s, though, so I can't
really say.

To tell you thr truth, I don't know, either. It might, at that. (The
center section, at least, the tips are removable, of course.)

Someone asked about a refueling receptacle back by the tail on the
F-8. First, receptacles are on the forebody, not at the back end.
Secondly, the F-8, being a Navy airplane, has a probe, not a
receptacle. It's on the left side, just below the cockpit, I think.

According to my F-8 Servicing Diagrams, there's an Engine Oil Tank
filler in teh upper aft fuselage, at the forward edge of the fin.
Perhaps the placard's associated with that?

The Single Point Refuelling connector was, IIRC, in the fuselage below
th wing, on teh right side.

We put a flight control computer in that space, after removing the
probe, on our F-8, so I'm going by memory of the dummy probe we
strapped onto the airplane for my PIO suppression filter testing.

To drag the thread a bit closer to charter, wasn't the computer used
on thw DFBW Crusader an Apollo CSM's Guidance Computer? I've seen
soem photos of the computer installation, and there's a suspicious-
looking DSKY in the computer bay on that airplane.

The page is gone, but my memory of the placard agrees with that
assement.

That was Phase I and it was three Apollo computers. Phase II was
three AP-101s. Although it really was more like eight of each because
we needed two ship sets (one for the airplane and one for the iron
bird) and a couple of spares.

Phase I demonstrated NASA expertise at scrounging and Phase II
demonstrated inter-Center cooperation. There's a photo of the F-8
DFBW in front of an Orbiter around that was taken for an article about
using the AP-101s. When Dave Scott left Dryden (and NASA), we gave
him his Apollo computer because we'd been in Phase II for years by
then.
