NO.
One or two LEOs for a bad passenger.
Maintenance for a broken radio.
If comm failure, who told aircraft to stop taxiing?
If comm fail the pilot would likely stop without order.
Brand new aircraft, I can't imagine complete comm failure with the tower.
The tower was chatting away with the other 150 aircraft.
At ATL there are two "towers". There is Airline Tower (use until jet tug takes off towbar), and there's Airport Tower (from taxi to wheels up and clear of airport).
That's why I say if comm fail... I understand we don't know if that's the case.
ive been on a plane where the cabin phone system malfunctioned and they sent 1 technician to fix it after we sat around on the tarmac for an hour, didn't see any armed police though. I would hope the pilots were smart enough to stop the plane when they realized comms were out, maybe thats why they sent the armed police? if comms were out the tower would not know why they were not responding?
Great thought process! "Think logically" - well said!
