You want to test your ability to get physical payloads in place, e.g. in the future the drone could carry a bomb or something else clever (listening devices? Dropping gallium on aluminum airplanes? Etc)

You want low angle shots?

You're not well funded enough to get good satellite photos?

> Dropping gallium on aluminum airplanes?

Is there anything that building a delivery mechanism to carry and then drop gallium onto a plane does that an actual gun wouldn't?

Befuddle the public with scary sounding words?

Hypothetically it might act as a more subtle form of sabotage, the goal being to bring down a plane in the air. It might also be harder to cleanup/patch than a bullet hole if detected. I don't think it's a serious threat though and is really acting as a stand in for "fancy forms of sabotage".

It doesn‘t need a clear vantage point with straight-line access to the target.

Less visible bullet hole more structurally compromised Al.

[raziel2701]

It's stealthier and quieter.

All three of your points make sense, but for me the last point really resonates.

No need for a space program, or going through someone that does.

Just acquire drone > use drone.
