Yes, but at 10:30 PM, I wonder how visible it was, and if it would have helped. It seems like many industries can't hire enough staff, putting additional workload on the existing ones, and forcing companies to hire very green staff.
Actually, those painted spirals are to mitigate birds strikes. I don’t know if there’s any empirical data to show how effective they are, but that’s why you see them on some airplanes and not on others.
When the spirals are spinning, they’re supposed to make the inlets look like eyes on the birds of prey.
To keep birds away don’t always work
It's the bait. People walk up it, to get a closer view; and Poof.....they're sucked it.
New regulations are not needed. There are Lines painted on the ground, that "humans" are not allowed in,when an engine is running. People either "shortcut", or are not properly trained.
“To Keep Employees Alive and Aircraft Intact, You Will: NEVER approach an aircraft to position ground equipment next to an aircraft or open cargo bin doors until the engines are shut down and the rotating beacon(s) turned off.”
It’s to hypnotize ground workers, to cull large numbers of them.
We have too many of them, you see.
