God
knows what it'll be like with even more. Assuming NATs can handle it which
isn't a given as it seems from 2019 they'll be doing London Citys remote
control tower - no one at home, just video feeds down a presumably "secure"
link. What could possibly go wrong?

Actually three separate secure links.

And how do you know the current one in use hasn't been compromised and is
feeding duff data or video? Or failing that a contractor cuts through the
cables by mistake.

If the cable has been cut through then you won't get any picture. I
suspect even someone from the CAA might notice that.

I suspect hackers would be somewhat subtler than just blanking the picture.

I was answering your point about the cable being cut.

What risks? Its a triple redundancy system as used by aircraft.
Whether the controllers re staring out of the windows or at screens
makes no odds. In fact the latter can be better as night vision cameras
can give you a better visual image after dark.

Right, because you couldn't possibly do any of that in the control tower.

Once you are using screens they can be located anywhere, don't have to
be actually at the airport.

And since when did security cameras have the same viewing field as the human
eye thats carried around in a skull and can look in any direction almost
instantly including vertically down?

And the advantage of being able to look at the foot of the tower would be?

You also have the possibility of overlaying relevant information on the
screens such as tagging the image of each aircraft with its flight details.

See above.

See what above? You haven't addressed the point at all.

I don't know, something happening nearby that may be of concern. Use your
imagination. The human eye is quite good at catching motion on the peripheral,
perhaps a vehicle or person where they shouldn't be etc. Something you won't
necessarily spot with screens showing narrow angle camera views.

The point being you could do all of that in the control tower. FFS, you can
get all that on flightradar24!

If you looked at the reports you'd see they aren't narrow angle views.

You still need a screen to to display it, once you accept that then we
are back to the point where it doesn't matter where the screen is
physically located.
