Needles to say it didn't work. 30+ years searching for these planes when they came to mind and I finally found them today. The internet is truly a blessing.

Imagine having such intense skill over ur craft, and you have a child who has a science experiment that ur probably gonna have to help him with. This could steal the show if it manages to just fly around non stop in a elementary school gym. Absolute unit moment right here.
I had a substitute teacher a couple times back when I was in grade school that would fly one of these around the classroom at the end of the day. It was so cool to see!
I grew up with the rubber band balsa plane models and went through many of them. My father made Sopwith Camel paper covered rubber band models, inspired by stories of his uncle from WW1. This is the space age version, amazing.
An episode of the great British egg race was dedicated to this and the building of your own plane which we did from balsa and cling film. The clutch mech on the elastic band was always the problem- we didn’t have any fancy winder though I’m talking back in the 1970,s Heinz Wolf was the presenter
"Our estimated flight time is approximately fourteen years, five months, three weeks, two days and forty five minutes so just sit back, relax and enjoy the ride."
Many years ago, I read that the covering is actually polyurethane finish sprayed on distilled water. I don't know how they pick it up, but that's the lightest material they can find.
Spray adhesive on a balsa frame. Had to lift it just right to break surface tension. Then cures on the frame in a rack in a box away from dust for a while. That was for thinned nitrate dope on water though.
Many years ago my dad went to a "penny plane" competition, where the maximum weight was 3 grams, the weight of a penny. The film you see wrapping the wings was so fragile in those days, if the plane approached you, you had to stand still and let it hit you, because the air turbulence you'd create by moving away would be more damaging.
For Penny Plane, that 3 gram weight (when I flew these, it was 3.1, the weight of a US penny before they switched to zinc) was a *minimum* -- that is, the model had to weigh at least that much. Like pretty much all competition classes, what started as a "beginner's" class (with the minimum weight and maximum wingspan) quickly got "competition inflated" to the point where there had to be a "Novice Penny Plane" with even more restrictions. Then there was P-24, with a plastic propeller and maximum span, and last I heard, P-24 airplanes were flying close to five minutes under a high ceiling...

If I had the money that's something I'd look into. Maybe I can suggest this to Colin Furze here on RUclips...
The propellors are very large, with lots of pitch, and the cross-section of the rubber is pretty small. The real trick it to make the airplane light enough to fly with a propellor that slow.
coming from slingshot background, nothing comes close to the efficiency of pure latex rubber for slingshot bands, or we'd use it. Pure latex rubber deteriorates fast, noticeable in months. Theraband is treated to store longer than a few months, but it's not as efficient. I'm calling BS on the aged rubber superiority. Tell me why I'm wrong though.
The claim sounds a little dubious at best unless the latex produced from the trees that year was due to a combination of an ideal growing season and maybe the solvents used being banned the following year leading to less durability in rubber produced from other solvents but as you said degradation over time would lessen the elasticity of the material, whether a silicone spray can protect the rubber from ageing is another question. It would be like a wine snob/connoisseur claiming to be able to tell the shoe size of the person who crushed the grapes from the taste of the wine. or an audiophile being able to tell from the sound of a cable whether it was cryogenically frozen during production.
