That sounds like a big risk to aircraft.

Shouldn’t be too hard to pull FlightAware data or similar and just not ever shoot within n degrees of aircraft… if it was really much of a concern to start with. Big sky theory.

Not all aircraft broadcast ADS-B positions.

And as a low-time pilot who’s been bit with laser beams from people’s Christmas decorations, I’d argue the big sky theory doesn’t apply here.

FlightAware doesn't show all airplanes that are flying, only ones with ADS-B receivers, which are not required.

Ah yes, the "star wars laser defense mosquito system". It' as impractical then (early 00's origin) as it is now https://www.youtube.com/watch?v=TGkPMZxWPpA&t=2s (it's Dutch but you get it). Unless you can get mm accuracy and perfect non-foe detection it's useless with the multi-watt lasers generally required.

Thanks for sharing this, but is a comedy skit from almost two decades ago - or any time period - really a valid method of debunking potential scientific progress made within that same time period? It reminds me of when people post SNL skits as proof of why [insert person inaccurately being made fun of either in a biased or exaggerated manner for the purpose of humor] is Actually A Bad Person. I mean yeah, the technology at face value is hilarious to think about, and goofy, but so are a lot of things that actually work pretty well.

I’m curious why you think mm accuracy and non-foe detection would be terribly difficult in 2021. Going off your example, I’m pretty sure a mosquito would appear rather different to any detection system than a human, or in the case of a field, a bee or something like that.

As far as I'm aware, this idea traces back to David Brin's 1990 novel Earth:

Realistic implementations use a cabinet with a generous intake and force air (and flying insects through into a controlled, confined space. After going around a corner or two, laser exposure issues are limited, and you can be close enough to aim effectively with limited optics.

Why not just use a mesh screen with a fan? Bugs generally don't fly with a lot of thrust to weight so they get trapped against the screen and die. I think NightHawkInLight has some videos about this on yt, though its definitely not some new idea.

If it has IR it should also be able to spot aircraft trails but either way if there is any risk of blinding a pilot then they should tread extremely lightly (or non-startup-ish, i.e. obvious potential for "move fast and kill people").

Flightaware’s api isn’t super cheap, that would add up if you’re calling the planes overhead API all day
