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.
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😱
PMMA, perspex was also used on the Spitfire cockpit canopy.
I'll refrain from using the n word😉
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.
