I've a solution
Mandate that UAVs either look like, or wear, little cyclists helmets, and then let loose a population of Australian Magpies. You'll have clear skies in no time.

"Three in one" because they combine a laptop, a tablet, and smartphone-like connectivity in one.
ASUS did this (more or less) with Android on some of its Padfone products. A smartphone with a dumb tablet "skin" that could then be attached to a keyboard.
The concept was abandoned years ago, but at least a Windows laptop is useful.
"Instead, it fell back to Earth, possibly still carrying its payload, and was destroyed by air friction, with the debris falling safely into the sea, we're told."
As a red-blooded Reg reader it would be remiss of me not to also point out that on re-entry from orbit, the heat and mechanical stresses come largely from compression of the air in front of the object rather than friction.
Early suggestions are that the Soyuz rocket performed its job and a flight control programming error in the Fregat upper stage (which is used with multiple launch systems) is likely to blame.
The final printed part is then first placed in a "debind" fluid that breaks down the wax and most of the plastic before being placed into a furnace where the rest of the binding agent (which has a boiling point of just below the metal) is burnt off, leaving just the metal.
Presumably the binding agent's boiling point is just below the metal's melting point, not its boiling point...
I think it would be an incredible coincidence for a stable multi-star system to form in the first place, and then after potentially hundreds of millions of years, for them to all go off within a few decades.
I don't know how close an ageing star would have to be to a supernova to be "set off" by the shockwave, or if that's even possible, but it also seems pretty implausible...
Pulsational pair instability was my first thought from a reading of the article, until I got to its mass. They're definitely right about the need to revisit that theory if it turns out to be the case, since this one is much smaller than the agreed lower mass limit for that type of supernova.
I particularly like the fact that pair instability supernovae leave no remnant, generating enough energy to completely disrupt the star. Returning all of a star's material to the universe in that way feels less wasteful than leaving behind a degenerate object like a neutron star or black hole.
