Here’s the same story without the WSJ paywall

Surpriseingly $80k is not unrealistic. The differential GPS in some of those little drones is worth $20k by itself. Looks like one of his drones is made by C-Astral in Slovenia. If it were USA made it would be $160k! But still that’s a lot of money for a fairly limited capability.
PS - I don’t mind paying for original content, but the WSJ just recycled someone else’s story. Why would I pay a subscription for that?
