Drat!  Comcast has that on the digital list and I'm not paying the
extortion for that.

it was sh.t on toast. poor history and melo dramatic crap.
they were measuring the intakes for a reproduction!
gee, anybody look up a chart and specs? they also said it was locked up "in a
high security site somehwere near dc!
you missed nothing.

While Wikipedia may not be authoritative, this jibes with my
recollections:

"The only surviving Ho 229 airframe, the V3, is located at the
National Air and Space Museum's Paul E. Garber Restoration Facility in
Suitland, Maryland."

While access to Garber is somewhat restricted (or used to be), its
certainly not what I would envision as the "high security" site noted
in the broadcast..

Yeah, that was pretty cool. They could have added another hour devoted to
just the fab/assy to suit my tastes. I missed the first 15 minutes - who
foot the bill on this project? And why?  Seemed strange, like they were low
on work and had some time on their hands and said WTH. - we'll settle a bar
bet and build a Ho 229 model.

And the answer to these question was found at...

    Hopefully it was better done that the one talking about
   the B-2 stealth bomber. In that one, the narration tried to
   portray the american aerospace community as completely clue-
   less to tailless aircraft, at least until one of the Horton
   planes were brought back to the states for examination.

    Completely fobbed off Jack Northrup's work in tailless
   aircraft. Acted like the YB-47 was first US tailless plane.

    Did they do an analysis regarding how visible the Ho 229
   would have been without the carbon in the leading edge, which
   I gather from the previews was the whole reason for the build?
   I doubt the British radar would have got a good paint on the
   plane, unless it was head on. But then, I expect that to be
   mostly the case for any flying wing design.

A tailless YB-47?  Hmm sounds like a what-if? build.  Maybe I need
another Academy B-47 kit. ;)
OTOH, Discovery was making like the channel I used to enjoy today with a
full day of prehistory shows.  That was so much better than their usual
schedule of crap.  If I wanted crap I could watch NBC which is Nothing
But Crap.

Wish they would have spent more bucks and built
a Northrop XP-79 ramfighter and compared the two.

Would have been nice and mentioned that the Brits had
Chain Home Low going at that time, plus a whole lot of
US Army AAA units potting buzz bombs with the SCR-584

----
The device had to send out 2,000 10-centimeter microwave
radio pulses per second. The particular system produced by
Chrysler Corporation was named SCR -584 and was teamed
with a heavy anti-aircraft battery of four 90mm guns, a British
invented IFF (identification, friend or foe) unit; a power source;
and an M-9 gun director. The scanning pedestal or antenna
mount, officially named Signal Corps Pedestal-MP-61-B,
turned at 1,750 revolutions per minute.... Once locked on,
the antenna tracks target evasive moves and synchronizes
the guns. The equipment was designed to cope with aircraft
speeds up to 700 miles per hour, up to 60,000 feet, at a
target distance of not less than eight miles. The secret
proximity fuse completed the ensemble,  since it was
effective if triggered within about seventy feet of the target.
---- from http://www.allpar.com/history/military/radar.html

Very few V-1s got past these once they were set up by London
and Antwerp: I don't see a V-1 having much more RCS than
a Ho-229, since it was also mostly wood, no cockpit and no
spinning turbine blades to bounce back RF

According to my father, it was far easier to locate a V-1 than it was to
track a Me 262.  Perhaps sound location tied into it somehow.  V-1s were
not stealthy.

Evidently they weren't very fast either, if you could run one down with
a Spit or a Typhoon/Tempest.

No, they weren't that fast, 350mph or so.

Problem was, that was at 2-3000 feet.

P-51Ds couldn't catch them.They were rated over 400mph, but
not down on the deck, but at 25k+. P-47Ms could, but had bad
engine troubles.
Had Corsairs been around, they would have worked too, but thats Navy

Enter Griffon powered clipped wing Spits and Sabre powered Tempests,
versions that did better at low altitudes, but not up high

I still don't understand what was the point of the build.
Non-matching materials, $2500-a-gallon paint, all the seams filled and
sanded in a way that never woulda happened on a forest assembly
line...that didn't strike me as a scientific exploration of the
stealth properties of the real thing.
Did our tax money pay Northrop to build this giant movie prop?
OldSchool - 29 Jun 2009 22:03 GMT
I saw parts of this truly disappointing mess.  So they wound up
putting it on a stand to analyze the Radar Cross Section.  What wasn't
clear (or perhaps I missed it) was how did the radar equipment used
compare to the actual Chain Home equipment.  My impression was they
used modern power levels and frequencies, which to me, seems not
viable "test".

by the time this was built, chain home was gone. some towers still remained
but don't forget, ww2 was the wizard war, so by 1944, radar was far beyond it.
all the variety was there, surface to air, air to water, air to air......
i suspect it would have been harder to see than a mosquito, those gave the
germans fits until very late.

I got the impression they knew what they were doing and that their
collective smarts on the subject exceeds ours.

No, actually,  it's an extremely safe assumption that the stealth folks at
Northrop-Grumman know more about the subject  than all of us put together.

As for the original question on the test simulation, someone has wiki'd the
project:

*****************************************

http://en.wikipedia.org/wiki/Ho_229
In an experiment to determine the stealth characteristics of the design,
Northrop-Grumman built a full-size reproduction of the V3 incorporating a
duplicate glue mixture in the nose section. After an expenditure of about
US$250,000 and 2,500 man-hours Northrop's Ho-229 reproduction was tested at
the company's classified radar cross-section (RCS) test range at Tejon,
California, where it was placed on a 15-meter (50 ft) articulating pole and
exposed to electromagnetic energy sources from various angles, duplicating
the same three frequences used by the Chain Home radar network of the
British in the early 1940s. RCS testing showed that an Ho 229 approaching
the English Coast from France flying at 885 km/h (550 mph) at 15 - 30 meter
(50 - 100 ft) above the water would not have been visible to Chain Home
radar, while a Bf 109 or Fw 190 was visible up to 129 km (80 miles) away.

With testing complete, the reproduction was donated by Northrop-Grumman to
the San Diego Air and Space Museum, while the TV special aired on June 28,
2009 on the National Geographic Channel.

Thx for the info...either that wasn't noted during the broadcast, or
(far more likely) I missed the statement of such.

As far as trusting the abilities of the Northrop engineers, I
subscribe to the "trust but verify" school of thought.

: I still don't understand what was the point of the build.

    Keeping folks occupied, rather than laying them off with
   pay, I guess.

: Non-matching materials, $2500-a-gallon paint, all the seams filled and
: sanded in a way that never woulda happened on a forest assembly
: line..

    Explain why using $2500/gal. paint made more sense than
   bolting a couple of sheets of aluminum in place of the paint,
   please? Oh, we already have the paint on hand, perhaps?

:        that didn't strike me as a scientific exploration of the
: stealth properties of the real thing.

    Did Horton use nails to keep the plywood in place?

: Did our tax money pay Northrop to build this giant movie prop?

    Apparently. On the other hand, we got to see the inside
   of a top secret hanger! Damn, but that made it all worth while!

    On the whole, it was the piece of dross that I expected
   the show to be. No attempt was made to explain why the proto-
   type crashed when it lost an engine, or how the Germans were
   going to solve the minor issue of the plywood delaminating a'
   la the Moskito. No attempt was made to compare the Ho229 to
   other plywood aircraft, like the Mosquito, or any of Jack
   Northrup's designs.

    And I had to love the farcical depiction of the Ho18 being
   accompanied by the Ho229's as they dropped nukes on New York
   and DC. All because the Dutch Uncle said that in 1946, the
   Germans would have a new-cooler weapon.

    Almost as likely as the Ho229 attacking the Chain-Home
   radar station on the coast, with narry a flak gun in sight.
