You need to put on quite a show to recreate 9/11. You need little to distribute biochemical or radioactive material, or fake distribute. Imagine a crop plane spraying some mass event. Let's even assume for the sake of argument it being simple water, before crash landing somewhere and a terrorist organization thereafter issuing a claim of responsibility and gloat about the irreversible imminent death of a million people. Would be interesting to see that play out. And yes, you would not need drones or crop planes necessarily, but it would probably instill more fear it being done that way. The gasoline attack (liquid fuel in general) vector in relation to agricultural planes (planes used to spray crops) is real though and the relevant part to your comment. Fly it into a full football stadium with 100k people, so small planes are not to be underestimated.
