> After all, what could possibly go wrong with remote controlled flying transmitters that interfere with GPS AND ATC navigation systems?

Do you think the people who operate or use these things are completely helpless and have no contingency plans?

The people in here saying the sky is falling are insane. People who operate disruptive devices are caught, and then educated and/or fined all the time.

Absolutely they have contingency plans and it's unlikely something with these would cause a jet crash, but in a scenario with instrument flight due to weather, taking out one of two additional positioning systems adds noticeable risk.

Low visibility. No GPS. Impaired ATC. How many additional separate systems have to be affected to be a real problem?
