> the drone could position itself along the correct precomputed vector from far away, cut off electric, and glide the bomb to the target silently.
An octocopter/ordinary drone can't do this - their electric goes out and they fall from the sky.
For a glider you'd need an actual flyable airplane model (something like this: https://laughingsquid.com/a-15-foot-long-radio-controlled-ai...), and these are expensive as fuck - a single engine alone will run up well into four digit range, if not five digits (something like the JetCat P1000). And at that point, you could also go ahead and buy an outright RPG, should be far cheaper to acquire depending where you are, or buy a couple junker cars, load them up with fertilizer bombs, and distribute them where one expects the target.
ISIS used[1] the X-UAV Talon. This is a off-the-shelf 1.7M wingspan drone plane available for about $150 without electronics (which are around $50-$200 depending on how elaborate you want to get).
It's capable of 100km+ flights[3].
Here's a pic of one after being shot down in Iraq[4]
