Planes were used in the world wars, then we have 9/11. This is the post 9/11 era where air travel sucks so much.
Similarly:
Drones are now being used in the Russo-Ukrainian war. Eventually, there will be a “9/11” with multiple coordinated drone attacks and then the way drones are treated will be forever changed. Civillian ownership of drones will likely be heavily restricted or entirely banned.
History rhymes.
Far easier ways to make/acquire gun powder, and far better explosives available. Fireworks make a lot of noise and light, but they aren’t particularly strong explosives.
But the ensuing video will be so pretty!
