It's all gone very quiet round here ...

A clue: it's been featured in this quiz before.

Sorry... toilet paper...don't have a clue.
Last week I got to see my second ACDC concert... the first one I went the next day because I messed up my calendar so 13 yrs later I finally did it !!!!!!!

Back to the topic: ...mhhh don't know....keeps ringing in my head "Shot down in flames".. sorry

Personally I think you got off lucky on that first attempt

If it helps, none of the aircraft's structure was actually made of toilet paper - just designed using similar principles. Chaps, can't anyone think of an aircraft that was soft, strong and very, very long?

Urm... the Gossamer thingamabob? The people-powered Channel crosser?

Another clue: it's a fighter.

Two weeks and we're no nearer to the answer! Either everyone's on holiday or I've really stumped you. Are there rules for what happens now?

Lets play twenty questions then
Is it to with the perforations of toilet paper. (say increasing laminar flow) ?

I know that the "toilet paper perforation effect" (it never tears in the perforation) is said to be used for increasing the strength of the reversing lids in the rear of the J 37 Viggen, but I guess that has nothing to do with the body or wings.

Tony

Jaypee: yes and no.

Longknife: closer, but you're right, it's the primary structure.

Soft = Zeppelin.
Strong = Led Zeppelin.
Very very long. Well that's relative right, and a A 12 Blackbird is relatively longest. Do you mean the not-so-tightly-riveted fuel tanks? Anyway, that's my best guess.

Tony

Ooh, getting colder again. "Soft, strong and very very long" wasn't a clue - it's an advertising slogan for Andrex. You may have been spared that (and the winsome little Labrador puppies) where you come from!

For "primary structure" read wing roots.

A wild stab in the dark. Argentine? Pulqui again?

Right hemisphere, wrong side of the Equator. Getting warmer again, though.

There is a F-16XL with perforated wings but that was part of the laminar flow studies.

F-18E/F uses perforated panels reduce to visibility to radar. Is that any closer?

A frayed knot. It's from the 1950s.

Ok. I have no idea where to fit the toilet roll in a F 104 Starfighter, but I get the feeling it might be it. Right?

Tony

Sorry, no - a little earlier and a little more wing than the Starfighter (although that wouldn't be difficult).

I'm just beginning to think this story may not be true after all ...

US Delta fighters ? dagger / dart ?

Bit further back than that. One more clue: the final version was the J.

You stumb them good Sean !

Ok. I yield! I've made a Google check on this guess, so if it's wrong I dunno what to do. Resign from the quiz, perhaps.

NA F 86 Sabre!

Tony.

(But where does the loo-paper go in that one?)

Ooh, bit closer than the F-104 was. So now we've bracketed it and all you need to do is work out which fighter between the F-86 and F-104 went up to a J model and no further.

Scorpion. It did have problems with the wing failing. Ends with J
Is that it? Everything is just guess at this stage

Go JP Go! Just so we can end the pain, please be right!

Tony

At last!

Yes, the F-89 had wing root problems, which they solved by drilling half-inch holes at six-inch intervals. The story goes that Northrop were absolutely stumped and resorted to using a suggestions box. When the holes worked, they wanted to know who'd had the idea, and they found out it wasn't an engineer, it was the janitor. So they asked him how on earth he'd worked it out, and he said, in twenty years of dishing out toilet paper, he'd never known it once to tear along the perforations, and if it worked for that ...

Jaypee, you have control, over.
