General Discussion

The FAA and NTSB are investigating the incident. Those drones will each have log data on them. I'm not sure what flight controller they use, but GPS data including several quality of service measurements is pretty standard in flight logs.

If it was someone with a jammer, the tricky part is going to be finding them. You can have a small, handheld, battery operated device. My guess would be someone did this as a prank and that someone else knows about it.
