It’s puzzling why there aren’t more airship drones for urban use. That is, guided balloons that would just sit over a city, digitally recording all vehicle and foot traffic for days.
Its purpose is not real time action, but to be able to record when an incident takes place, where the bad guys have come from, and where they go after the incident. This would compromise every building and vehicle used by the terrorists.
Without such buildings a vehicles, they are neutralized, and just need to be picked up.
