> The surveillance video that is circulating shows that the system was working and indicated that the runway was not safe to enter. A citation, please? The only video that I know of is [1]. [2] is my best mock up of the only video I have. I'm am not an expert, but my best read of that is that the RWSL is maybe? green to the taxiway¹ traffic, so, to me, the actual status of the RWSL at the time of the incident is "unknown"; that seems like something I should wait for the NTSB report, or at least someone with expert knowledge on. But your claims doesn't jive with the evidence I have, so that's what makes me ask for a citation. [1]: https://www.youtube.com/watch?v=jRl7Vr87ym8&t=29 [2]: https://imgur.com/a/RVL28AV ¹but I think there are a number of problems with my own interpretation: I could be wrong about which lights are which; I am using the near-side lights, not the lights on the side the truck is entering from, and assuming them to be symmetrical (though what little I can see of the far side does seem to align with the near side); some of the lights I think are RWSLs & not RGLs look downright yellow, but that could be a property of the low quality of the video; there's the rather large problem of the plane on the runway that must then be explained. |

Sorry for the late reply, and sorry for linking to reddit, but it was the first place I could find the right video. I saw this video linked at least a dozen times in the hours following the incident. I believe the clip you linked to is from the same video, but with the beginning cut off.
At approximately 1.5 seconds in my link, you can see one set of lights perpendicular to the runway turn off. I admit the the lighting/colors are not as crisp as I would like, but the lights that turn off are positionally consistent with the Runway Entrance Lights and the time at which they turn off (approximately 2 seconds before the plane enters the intersection) is also consistent with the operation of the Runway Entrance Lights system.
Furthermore, if the system was not operational it should have been NOTAMed as such, and I can find no such NOTAM so my default position is that the system was operational.
