Ehhhh, the aircraft flew into the trajectory, are there no other comparable scenarios where there's an intersection that can happen accidentally?

Basically, if you're planning on pointing a laser into the sky, you need at a minimum issue a NOTAM to inform aviators of the hazard. Things like outdoor concerts and some weather observation systems do this.

But... Sending a laser into the sky and intersecting an aircraft that was operating per regulation? That's on the laser-er, and "creating a hazard to aviation" is not a charge that you'll be happy dealing with in many countries.

Doesn't really matter if you're across the globe...

This would be rare and it would only affect the pilot if the laser was tracking the plane as it flew overhead.
