If school busses can look both ways before crossing train tracks you'd think a firetruck would look both ways for airplanes coming down a runway. Don't want to blame the firemen though - this was a series of extrmeemly unfortuante scenarios and people trying to keep the airport running safely. For years people have been on soap boxes saying the FAA/NTSB needs to do better, and yet year after year they are poorly run and poorly funded.

A quick Google gives me that a 737 typically lands between 144 and 180 mph. I think that's quite a lot faster than most people are watching out for. Good news is they are bigger than cars and so easier to spot at a distance but I'm still skeptical that "look before you cross the runway" is sufficiently safe. Keep in mind that the planes may not even be on the ground yet - at the top end in 30s they could go from a 1.5 miles away in the sky (and up to 300-400ft in the air) to plowing through your position (iirc runways are about 2 miles long for jets).

I wonder if it'd even be reliable to see such a plane coming fast enough.

Now multiply that by the dozens of planes in your vicinity, and by the 100ish big US airports.

That isn't even beyond the top speed of a car, which non-trained humans are very well capable of tracking by sight - to talk of airport workers that are specifically trained to look for air traffic. It really is not that hard to tell that an aircraft is on short final if you are actually looking at it.

With four miles of visibility in light rain at night, the aircraft should have been perfectly visible (in a vacuum); what remains to be determined is why the ARFF crew did not see it. The answer to that could range from "they didn't look at all" to "the orientation of the runway relative to the surrounding neighbourhoods meant that the CRJ's lights got lost in the city lights".
