Major U.S. airlines warn 5G could ground some planes, wreak havoc | Reuters

“Multiple modern safety systems on aircraft will be deemed unusable causing a much larger problem than what we knew… Airplane manufacturers have informed us that there are huge swaths of the operating fleet that may need to be indefinitely grounded.”

One area of concern is whether some or all Boeing 777s will be unable to land at some key U.S. airports after 5G service starts, as well as some Boeing cargo planes, airline officials told Reuters.

The airlines urged action to ensure “5G is deployed except when towers are too close to airport runways until the FAA can determine how that can be safely accomplished without catastrophic disruption.”

This sounds a bit like Y2K, except that it might really happen.
