I was excited to see some evidence, but if you actually read the article they're talking about flakes of silicon with less than one joule of energy reaching the surface. To break an airliner windscreen, you need an energy more like a big hammer.
> In one rare instance, the company also revealed that "a 2.5 kg piece of aluminum" found on farm grounds in Saskatchewan, Canada, was traced to a Starlink satellite.
A piece of debris of similar size to this is what I'd guess could cause the kind of damage we see in the incident involving the airliner.
So while most Starlink debris may be harmless by the time it reaches the surface, we know this doesn't always happen as expected.
And since the vast majority of reentering space debris is from Starlink satellites, that'd would be the first place I'd look.
To be totally clear, I am doubtful this is actually caused by space debris, but I don't think it's entirely unreasonable for it to be one of the most likely causes.
