So, after seeing this xkcd question...
What if you strapped C4 to a boomerang? Could this be an effective weapon, or would it be as stupid as it sounds? —Chad Macziewski
Aerodynamics aside, I’m curious what tactical advantage you’re expecting to gain by having the high explosive fly back at you if it misses the target.
At first this sounds really stupid, but C-4 is a very stable explosive, requiring heat AND shock to trigger.
So the question is, with modern tech, Could a C-4 boomerang arm/disarm itself reliably/fast enough to blow up a target on a hit, but not blow up the thrower? (or hurt the thrower when it blows up due to shrapnel or other explosion related injury)
For 'Practicality", lets say this is for use by a secret service agent for whom money is not a problem.
