Before your head-smiley smashes in the brick wall...
Many airlines (including SouthWest!) have WiFi networks in the aircraft.
I'm sure dozens of aircraft are crashing daily and thousands of passengers have died as a result.
What frequency is WiFi? Oops, 2.4 GHz (and 5).
Time to wake up and smell the 21st century?
On aircraft tested and certified for use. On others you are flight testing with a cabin full of passengers!
I'm well aware of what is and isn't available on fleets across the globe thanks!
