That's a clever one. More importantly, it makes for an amusing picture.

Not as cool as hunting birds though, which is being tried too. Drones are probably more practical, I guess.

Now you have two problems, as in "Engine 1 ate the drone, while Engine 2 ate the eagle."

I've seen that, but wouldn't a laser actually be more reliable / faster?

Well like arjie said, you don't really want flying debris near people/runways

And maybe the energy necessary to actually vaporise entirely would not be the kind of thing one would be wanting to punch up into the atmosphere willy nilly.

Not to mention that you actually need an actual cannon, not a pointer. http://www.defense-aerospace.com/articles-view/feature/5/159... Yup, that's definitely something you want to mess with around an airport. "Wait, I was supposed to shoot down that other blip?"
