Airplane mode is meant to protect the cell phone antennas on the ground. 200 phones logging themselves into the nearest antenna at 500kph acts as a solid DDoS. Definitely not needed at high altitudes, but maybe it was 15 years ago

Lol. Antennas near subway and train stations must be totally screwed then
The antennas are in the stations and in the tunnels, and they’re built for that load. I agree that it’s not a big problem for telcos anymore
