Incredibly to the point. This was my second favorite. The objects conveyed the concept of the plane, the color choices (I believe, no color blue and surprise pink) combined with the placement of lights were spot on with their word.
Theirs was probably the only setup to efficiently use the change of color temperature and intensity over time to convey the urgency and the danger. I don’t believe they used any down lights, but they did use 4 lights all around.
Honestly though, I’d prefer it a lot if the backlight aimed near me didn’t flash so much. It was starting to give me a headache.
