It's from Bratukhin, it's based on the Omega II but it has a different designation...you're almost there...but not yet...

Okay, I've had to Google it:

The Bratukhin G-4?

You're nearly there... a little help:
It was based on the Omega II or G-2 .
The G-4 was build after the photo subject...
Can't help more than this without giving the answer...

Ummmmmmm ... G3?

Got it !!!!!!
Up to you now !!

Well, that was what we in the artillery calls a fork. A little far, a little near, a little further, and WHAM!

But for myself - never heard of the machine Tony

While I was searching for another Quiz Theme I found that strange looking bird...

Okay: Obscure Early Rotorcraft Part II ...


What is this?

Bell XV-3 ?

Not a Bell XV-3, but it is the same tilt-rotor concept.

That's planes not mental!

Jaypee's got it! Good on you.

Now it's your turn ...

Ok. Not really prepared for this but here goes.

Why do sparks fly in Krakow?

Because that's where PZL built the Iskra, which translates as "spark"?

close enough. the sparks are flown by the polish aerobatic team at krakow air shows.

be doing blue impulse sabres of japan

over to you sean

Oh dear. Another quickie, then. Which two jet aircraft had their engines stacked vertically?

EE Lightning is the obvious one.

Are we talking pure jat? There were a few hybrid jet/rockets that had their engines stacked, Mirage for one.

Pure jet, yes - no rockets or other funny stuff.

I believe one of the Ye-155 prototypes (during the development of the Mig 25) had stacked engines, and the other is the Lightning, as Graeme says.

Not what I had in mind, I'm afraid. In any event I have me doubts about the Ye-155. The first prototype is usually listed as the reconnaissance variant and all the illustrations of it show basically a conventionally laid-out MiG-25. Given the aerodynamics of the intakes, stacked engines would be nearly impossible - but now that you've piqued my curiosity, I'll check...

Have now checked and I can find no trace of a Ye-155 having stacked engines, even at the drawing stage. Though with Soviet designers anything's possible.

Clue, anyone?

Clue please! The only thing spinning in my mind are the concepts from Gotha during WWII, but I can't believe any of those were even built.

They're both British.

That'll be the lightningEE and the shorts sperrin.
A bomber of such beautiful lines it could only be built in Belfast.

Umm ... beautiful? And have you seen the Skyvan? That was built in Belfast too ...

But you has it, congrats, over to you!
