Yeah - I'm sure they do and that is my point. The heads of Verizon
and ATT are not flying commercial. Their planes are not commercial
airlines with hundreds of passengers == so they can much more easily
just divert...<br>

Considering Verizon has a very sizable fleet of private aircraft,
I am fairly certain this will happen often.

Scott - a side note to clarify things... <br>
<br>
The 737 Max8 problem was NOT due to lack of testing or
non-incremental changes. The system was well tested and put
through it's paces. It was a lack of proper pilot training
in the aircraft and its systems and some carriers choosing
to NOT purchase specific flight control options.<br>
<br>
Full disclosure - my classmate was the Chief Test Pilot for
the MAX8 and another classmate is the current FAA
Administrator.<br>
<br>
But I digress - sorry...<br>
<br>
If you look at 5G deployments around Japan and Europe,
generally they are NOT right up next to major airports.<br>
<br>
I would like to ask ATT and Verizon senior leadership to put
their loved ones onto a commercial aircraft that is flying
into ORD during a blizzard on a Zero-Zero landing (the
pilots relying on radio altimeters) and the 5G network up
and running and then ask how confident they are that NOTHING
will interfere and 5G is perfectly safe.<br>

I worked in aviation as a technologist. Aviation is
resistant to change.<br>
Any change. When you fly older aircraft, be aware
that the software is<br>
old. Very old. As in some of the vendors long ago
stopped supporting the<br>
software kind of old, assuming the vendors still
exist. <br>
<br>
Aviation didn't wake up one day with the sudden
appearance of 5G. They<br>
knew it was comming. They, aviation themselves, are
heavily involved in<br>
standards. Aviation had plenty of time to test,
correct, and protest.<br>
<br>
What aviation now wants is a 5G exclusion zone
around airports, or what<br>
I sarcastically call "a technology exclusion zone,"
which tends to be<br>
businesses and homes. What is aviation going to do
when 6G comes along?<br>
A new WiFi standard is implemented? Any other
unforeseen future<br>
wired/wireless technologies? Or perhaps cell phones
should go back to<br>
Morse Code for aviation's sake?<br>
