I thought this belongs here

Looking at those asymmetric planes,

Holy crap.
Here I was thinking you had shown this in regard to the Burning Amp Festival letters on the plane.
I was going to ask where to buy tickets.

And there was I thinking you thought that BAF stood for Bonded Acetate Fibre! 😉

Airbus Beluga. Jet powered Super Guppy AFAIKT. I've seen one of these IRL and it looks as utterly implausible as it does in the photo.

Early on in my time in the drawing office and without much experience designing injection moulds, I questioned Bill my older and vastly knowledgeable colleague who had worked for Ekco Plastics in the past, how do you work out how much steel to use for the bolster (the frame of the mould). His answer was if it looks right...

That don't look right.

Same goes for those ridiculously massive cruise ships😱

Of course I was on the BAF, but it’s nice seeing a thread like this meander 🙂‍↕️
So:



And

Yes, lots of perspex on the Lizzie!


The inboard wing tapers would also have improved the field of view.

PMMA, perspex was also used on the Spitfire cockpit canopy.

I'll refrain from using the n word😉

Supper Guppy? Boring beside the Howard DBA, just a shame it was never built.

Wide body Hernia plane.
Could have used that when they moved the London Bridge to Arizona.

PMMA, perspex was also used on the Spitfire cockpit canopy.

Your mention inspired me to learn more about Spitfires that were converted for the photo reconnaissance role.

Weapons were replaced with fuel tanks to give the Spitfire an exceptional range. They were able to fly all over occupied Europe to determine the status of the RAF’s and U.S. Army Air Forces’ bombing missions.

Without weapons, though, Spitfires could be sitting ducks to anti-aircraft fire which led to them being painted pink to blend in with the sky at sunrise and sunset.

I read it here: https://www.wearethemighty.com/migh...to reconnaissance and bomb damage assessments.

P.S. I had to look up the acronym PMMA to find that it stands for polymethyl methacrylate.

AKA acrylic.
It's the latest fancy term for a type of waterproofing system that would have gone by the wayside had it been labeled as such.
PMMA systems easily sell for three times what something called acrylic would

 

[Galu]

Perspex should strictly be written as Perspex®, indicating that it is one of the registered brand names for cast acrylic sheet.

The name Perspex was first registered in the UK in 1934 and became a synonym for acrylic in the same way that Hoover is synonymous with vacuum cleaner.

There are other registered brand names for acrylic of course, including Lucite® and Plexiglass® which are better known in the U.S.

Finally, did you know that the word perspex was derived from the Latin perspect meaning "to look through"?

Learning all the time!
