Almost don't want to fly on Boeings ever again...
""Airbus and Boeing have been working with other aviation industry stakeholders in the US to understand potential 5G interference with radio altimeters," Airbus said in a statement."
That said, this is Boeing's fault. They need to clean up their act ASAP, and it seems like they've been banking on the FCC covering up their mess and are now running around with their hair on fire.
A reasonable stopgap may be to simply not allow 5G towers to use the frequencies ranges in question within some radius of an airport (20 miles?) for a few years until Boeing fixes the problem.
