Ok, well let's rephrase that: it would be trivial for me and I hate to underestimate the opposition, they're not all dumb. And the proliferation of IEDs in Iraq suggests that those skills are readily transferable.
If you need more than around 200feet of range, a coathanger as an antenna at each end could probably triple that range, a couple of coathangers fashioned into a pair of 310MHz yagis could likely get you several miles range.
All for less than a Raspberry Pi camera.
Even if you, as a "smart guy" were also a bad guy, would you _really_ consider doing things "the hard way"?

Nope, there were a small number of bomb makers who provided the bombs to a distribution network - this network then assigned the bombs to emplacement teams. There was also state level assistance coming from Iran. A few bomb makers and a lot of emplacement teams blew themselves up - so it isn't as easy as Hollywood has portrayed.
ADB-B receiver + cheap drones with simple homing software = total shutdown of US air traffic. I think $20,000 is probably an overestimation of what it would take. There's a lot of asymmetric situations starting to "mature" and defense side is way behind since they're using them to exploit the populace. It's not just a "cyber" problem.

The "bad guys" already know reliable ways of long-distance remotely triggering IEDs: https://www.google.com.au/search?q=IED+trigger&num=100&tbm=i...
They're using those cell phone we all threw out 10 years ago. (I think I see a dozen or more of my old Nokia 8210 there...)
