On: How a Mexican Drug Cartel Makes Its Billions

Well...the drones aren't exactly huge, and they're flying really high up in the air, so it's doubtful that you'd see them.

The MQ-1 has a wingspan of two dozen feet, and a service ceiling of 26,000 feet. (ten thousand feet lower than a 747) It's also got a pretty tinny piston engine, with a fairly distinctive sound.

Think more "cessna with missiles" than "RC plane".

EDIT: Just checked the wikipedia pages for both:
