Go to college as soon as possible, get a degree, and then leave the United States to earn some cash in another country that does not insist on ruling the world. When you have enough cash, then look for a good university in another country outside the United States or the United Kingdom (you will find its affiliates all over most of the world). Or as I did, work at McDonald's and study by yourself instead of chasing papers. I stayed in university for 8 years, just to study the laser pointer instead of getting a degree.
Use it as a plot device. Except they used a small portable telescope and a camera flash, and triggered it when the plane was about to land. The telescope is used to collimate the flash so that most of the flash energy is in a narrow beam. This may be an effective terrorist weapon, but it may not achieve long-term success. The same equipment that allows welding Google to darken the moment the spark is hit can be used to make goggles.
The question also mentions the angle of the cockpit windshield as a potential problem. I don't think this is a problem at all. This boils down to the distance and angle between the criminal and the plane. If the pilot can see where the criminal is on the ground, then the criminal can illuminate the pilot with his laser.
I used the word crime many times in answering this question. I did this to point out that irradiating a laser on an airplane may seem like a cute little prank, but in fact it is a serious federal felony. If you are caught committing this crime, you will have a lot of time in the cell to reconsider how cute it is.
The various elements of the eye are not very "good" optically, and the angular resolution is also very poor-which means that the focal spot size is large. The laser beam does not form a clear focus on a single green laser pointer (such as in the human eye, which will cause a hot spot like a magnifying glass under the sun), but focuses on a blurred point behind each element behind many elements. Compound eyes.
It is much more difficult to cause burns in this way, because the energy is dispersed to many less concentrated points instead of one very strong point. In addition, compound eyes are highly redundant. It is possible that even if most of the receptors are burned, the eyesight of the flies is still usable enough to not notice the difference in fly behavior.
