The discussion Mark and I had about the design for that UAV involved a discussion of current ducted-fan UAVs, which Mark declared "look[ed] like...Hello Kitty UAV[s]."
We hope this one is more menacing. For one thing, it's the size of a delivery truck, instead of the size of a bucket, which is how big some real ducted-fan UAVs are.
Aw, don't look so sad, Isabel. Who needs a stupid UAV, anyway? S-stupid!!
Here's another interesting and popular fact: I hadn't decided until the last panel whether Isabel was still wearing that dress instead of a full set of body armor. But body armor wouldn't get blown around by the gusts of wind quite so effectively.
