And yes, we did have this quite recently and the response to "was it during covid?" was that if it was, everything would have been parked up as almost nothing was flying
My recollection was that we postulated that it was indeed during Covid but then someone in the industry came along and said that during Covid it was like a plane parking lot and they couldn't move for them. I don't actually remember what we concluded though.

However, if you look at the entirety of the Heathrow site, which is around 5 square miles, you find no cars in the car park and not a single plane other than Concorde sat where it's always sat. This would require that images are taken at the exact point when there is no cloud cover over a part of the airport where at that precise moment, no planes, ground transport or cars are present.
Whilst not impossible, I do find it improbable.
My working hypothesis is that the collection of images do not make a particularly good total image, most likely because of different light on each pass. So the Google system makes an image using what it has and creates the missing parts itself. It's unlikely that it would recognise the image to be an airport, just seeing pixels. So, if the good images are indeed devoid of planes, then the bits it creates will also be devoid of planes as there's no reference pixels to replicate.
On Google Earth the history slider shows that the image above was taken on 04/2020, and that it is being used for the "current" photo - with no aircraft showing, whereas the history slider shows the latest image being 07/2022 with plenty of aircraft and vehicles.
No idea why the earlier image is being used as the current one though.

What the flig went on in New Zealand that they have [had?] so many extinct birds ?
Food mainly. NZ doesn't have any indigenous mammals except bats. Early Polynesians discovered a lot of flightless birds as a result of no predators. They discovered they were easy to catch and tasted rather good.
With the introduction of other mammals and farming methods, the bird population inevitably suffered.

It's never been a thing. It's an urban myth.
Never? Not once in the 100-odd years since electric traffic lights were first introduced? That's a very bold statement. Flashing your lights at a light sensor (because it hasn't already picked up your approaching lights, obviously) makes traffic lights change in the dark. Ok.

Dipped headlights and main beams illuminate the same distance? Ok. Flashing your lights at a light sensor (because it hasn't already picked up your approaching lights, obviously) makes traffic lights change in the dark. Ok.
That aside, it was a simple enough question; have temporary traffic lights *ever* been equipped with light sensors, even in the dim and distant past? It's a pretty bold statement for you to say that, no, never at any point since they were invented has a set of traffic lights ever been equipped with a photodiode or other form of light sensor.
Anyway, no matter. I was just interested in knowing if the myth had any kernel of truth (because sometimes they do).
