at least one article stated that 28L had its threshold lights (??) configured to a huge 'X' to additionally indicate that 28L was closed... that should have also been a clue to the A320 pilot that they were lined up wrong...

yeah, we don't know... that's plausible but there's no time information given for proper timeline evaluation...

ahh! i found it... atlas obscura is where i saw it noted as 16x16 but you made me go hunting again and i did find the 17th column one mile further east and another row one mile further north so i had to renumber everything but i do have a KMZ file from google earth if anyone is interested in it... i've found 144 markers, i think... the rest are just not visible at this time... either (re)moved or covered by sand...

well, how about that... you are right! i just went back and read it again... i have spent the last half hour trying to find, again, the references i used that told me the grid was 16 x 16... it is apparently 17 x 17 which means i have another row and column to try to find... as for determining the NW origin, once i found one of the Maltese Xes, i kept going west until i found no more... then i went north until i found no more... eventually the NW corner basically showed itself to me... but i'm also wondering if maybe i have actually found the NW corner but it is not an X... slightly offset of where the X would be, is two long pads like a vertical equals sign but a bit larger... i'd love to find the map that they used in the article to determine what and where the markers were... i just started the project after reading the article and others related to it... it is funny, in a way, because i was out that way back in the '80s and could have actually walked to them at that time...

where did you get 273? my understanding is that the grid is 16x16 which is 256... FWIW: i've found and marked 135 of them in my Google Earth installation... i started my grid in the north west with each row being letters and each column being numbers... of the A row, which is beside the Gila Bend Hwy, i found only one remaining marker (A3)... none at all of the B row... farmland and the population area of Casa Grande took out most of those rows... Arizona City took out a large section of G8 through L16 in that particular grid box... plus there's a canal or two that took out several when it was put in... i still go back and look for more of these markers from time to time... unfortunately the google earth imagery only goes back to 1 May 1996 so any that were still there before then are just not available in the imagery to be marked... they are all on 1 mile placements, though... that's easy enough to see... the real trick is to figure out which corner of the intersection they are o

FWIW: here's a few links to these very similar markers... http://sometimes-interesting.com/2013/12/04/concrete-arrows-and-the-u-s-airmail-beacon-system/ https://en.wikipedia.org/wiki/Transcontinental_Airway_System https://en.wikipedia.org/wiki/Airway_beacon http://www.dreamsmithphotos.com/arrow/arrows.html

they should go find the airmail route markers and do a story on them, too...
