I suppose that I probably won't will allow that, because copyright issues. This is Japanese version of West Coast Images Web of Secrecy: YF-23 Black Widow II Declassified documentary - money from sales of this DVD go directly to Northrop veterans who did this enormous effort of digging ATF-23 archives. So piracy in this case will directly affect their wish to continue research. Moreower, I know these people, so it just won't be polite. Publishing couple of promotional screen captures is OK, but posting video is no-no.

IMPORTANT NOTE
DVD is discontinued, WCI Productions web-site is RIP. So grab your copy before it's gone! Some e-shops still has it to offer.



No.  It's not the Web of Secrecy video.  It's a tv program documentation of modern military planes in general.  Geography, I believe. The vid features the rafale, then the typhoon, then the yf-23. 
Edit: and beside, I wouldn't be that stupid.  Some folk did that a while ago on youtube and got account deleted :D

Who made that image?
I know for a fact that it is a fake.
Mainly because I used the same background image ( of the hangar)
It is quite easy to find the original image on the internet.

This is the tread abuot my favorite aircraft and in the last 7 post there is not a single mention of the word YF-23.
Those kind of replies are better of as PM in my opinion.

I jump on every alert of a new post to this tread only to find talk about Trojans. Very upsetting to the quality of the forums

My apology, mate!

Here's the video I said with a scene where the yf-23 opened its weapon bay inflight for anyone who's interested (I contested the youtube copy right search engine for the music I used and I really don't know about the future of this video):

Removed some recent off-topic posts.

YF-23 was certainly a beauty.

I found this on a japanese website with pics inside the cockpit:

There are also part 1 and 2 at the bottom of the page, but not much to see.

Sorry for my ignorance, but does anyone know why it has 2 variable nozzle flaps on top? How do they work?

Read first something of how nozzle works in common.
Then look at the picture of F-15SMTD PW nozzle and keep in mind that this was a derect predecessor of F119 nozzle installed on YF-23A PAV-1. Look here as well http://www.secretprojects.co.uk/forum/index.php/topic,212.0.html
This should answer a question why it has 'two flaps'.

Thanks alot for answering question, man! So the 2 flaps were some sort of convergent/divergent nozzles for speed handling?

I don't understand the point of this post.  Is it just to correct my choice of phrasing words, or is it trying to show some significant difference in "sort a convergent/divergent nozzles" and "convergent/divergent nozzles itself?" Please explain if there is a difference!

Actually, the bottom flap wrt to the rest of the nozzle is what would have made the convergent divergent section of the nozzle. I'll have to look at the images in the other thread when I get home, I can't see the images at work, but the separated area between the two nozzle flaps is most likely where bypass air exited to "cool/shield" the heat signature from above.
