I assume you are referring to the fact that cardboard drones powered with rubber bands are believed to be used to deliver explosive warheads to Russia.

Wish I put more effort in studying paper & cardboard planes in primary school.
I put a lot of study into both distance and acrobatic paper plane flight when I was in high school. Unfortunately all it got me was detention for littering the school oval :(
While we were firing off custom modified increased altitude rockets, which one could simply buy from hobby shops in the 1970s, from Tania Park - North Beaches, Sydney, after school.
It was also a very interesting period. Crater Cove, when the wind was from the south east, there were numerous people flying radio controlled gliders & planes. A few years later & still to today flying hang gliders or mostly air pillows.
We were at the pauper end & could only afford missiles, with a guestimate of 3km altitude, could not see them anymore with binoculars (well within flight paths), with live landing payloads on parachutes (mice all survived... shaken but not stirred, so to speak). We actually on a couple of flights had two stage rockets. This was primarily a school fun.
But would have preferred to get into radio controlled flight if we could have afforded it.
Anyway I saw a few mid air collisions of gliders & aeroplanes. It looked like confetti in the air. Pretty sad for the owners aircraft, as they all had endless hours of custom construction.
My brother did get into radio controlled flight to some degree. A bit of competition.

I flew model planes for years.
Early 2000"s came lithium batteries and electric planes made of Styrofoam , along with then, a complex way of matching controllers.
So off flew my Cessna and some minutes later a trail of smoke followed it. The controller caught fire and it crashed.
There we were, 8 flybys running to put out the paddock.
As to the Ukraine situation I'm waiting for a fleet of such cardboard planes to kamikaze the Kremlin.

I still have my motors (plus some planes and equipment ) from the early 1960's.....
The Taipan 2.5 with the "pink" fins was my first model aero engine in 1960. That lead to several years and lots of enjoyment from Control Line model aircraft. I have always liked the Diesels but the Glow Plug motors I had later were always a bit less temperamental. I remember the OS Max 29 and Glo Chief 29 as great, super reliable motors. My interests changed once I was old enough to get my Drivers Licence and a car and that started my involvement in Club motorsport which has continued to this day (who would have thought....)! All been good.
They were solid fuel rocket engines in cardboard (solid fuel is what the current rocket systems are trying to use). We could buy them from the toy shop from Warringah Mall shopping centre (like any other suburb shopping centre), Sydney Northern Beaches.
We modified the rockets to create a 2 stage rocket. Both fuses lit at the same time as the second stage fuse being a whisker longer, only needed about a 1 second delay maximum.
Including chlorine bombs, pipe bombs, & the list goes on. All in the bush. There was never a OH&S issue. Us primary school children actually had common sense in the 1970s.
We just had to be home by dark for dinner. So there were no safety issues.
In the scouts we set up 240v supply in the bush. There were always questions from other scout groups. We always said 'Don't you have 240v ?!!!'.
We had batteries & inverter hidden in eskies.
Had not thought of refrigeration in those days. But once faked it with ice. We were pretty mischievous.
I still think our long distance catapult egg launcher was the best fun. The many hundreds of eggs did hurt the pocket money, but it was worth it!
