De Havilland DH.127 and DH.128

According to Derek Wood; Project Cancelled, pp.190, 192-195, the DH.127 was a two-seat V/STOL strike/reconnaissance aircraft with high-mounted delta wing, twin reheated Speys and two lift engines in front of the cockpit. Joint RAF/RN requirement OR.346 led to Ministry Specification ER.206 for an associated research aircraft, and it was for this that the DH.127 was submitted. (The other contender was the Vickers-Armstrong Type 581 variable-geometry design, heavily influenced by the work of Barnes Wallis). According to the linked Type 581 thread, the year was 1959.

Detailed features of the DH.127 included thrust-vectoring nozzles near the front of the Speys, apparently bleeding off cold air from the compressor, Mirage-style semicircular intake shock cones, folding wing tips, drop tanks and arrester hook. Its multipurpose weapons bay could accommodate a small nuke. Judging by its size relative to the Speys it was a fraction smaller than the Mirage IV and one could be forgiven for thinking it a V/STOL variant of the Dassault bomber.

The DH.128 was later submitted as a specifically naval design, in competition with the similarly revised BAC (as Vickers had now become) 535 VG proposal.

Can someone please make all the planes from Jane's Encyclopedia of Aviation?
I would really like it if someone could do the second edition which first flew in 1993, but if they wanted to do the first edition that first flew in 1989 that would be fine.

And all ships of the Jane's Fighting Ships, please.
OK, you can omit some auxiliary vessels... but not the tankers, because I love them!

Guys I would appreciate if you stop picking on me. Next time this goes to the admins. i will say this again. This is a request and for ideas. it does not have to be acted upon. It can take 50 years. I will be dead by then, This is for the newbies who want to try their hadns at modding, not just me.

This you dsawan?  Posting mods and maps on another site?
Then you can keep all your requests quarantined to that site.

As far as I can see .... He is only posting links to stuff here .. which to be honest any normal player on that site would have found anyway.

He is simply another "no talent wannabe" trying to make himself look like something he is not .. or will ever be. He is not the first and won’t be the last sadly.

Your words are unimportant. Nothing changes. BTW you should adhere to the guidelines posted here in this specific forum beacuse you are going back to it and should not be happening again on flaming or picking on another member. see here:

"That is because we are all still enthusiastic about this game, and it's subjects. The planes, the bullets, the bombs, the stuff! This section has also, rather sadly, become a kind of a newbie trap, where over zealous people get to stomp all over requests that are perhaps a bit over the top, or not structured in exactly the correct way, or just outside of another's taste. This will now end. Trampling on the enthusiasm of another IL2 lover is, quite frankly, a bit unforgivable."

I have not violated any guidelines so if a moderator steps in I will cite this in defense.
