@Whoop whoop pull up: I'm trying to add coords to the article. The NTSB report gives 41°47′26″N 71°38′10″W / 41.79056°N 71.63611°W / 41.79056; -71.63611; however, this location is on dry land, and a mile closer to TF Green than the distance given. Are you able to find anything that might resolve this discrepancy? Pi.1415926535 (talk) 23:25, 20 September 2021 (UTC)Reply

Can't help you with that, I'm afraid - I'm going off the NTSB report myself, and encountered the same problem (hence the commented-out coords in the infobox).  :-/ Whoop whoop pull up Bitching BettyAverted crashes 01:16, 21 September 2021 (UTC)Reply
Okay, good to know. I've removed the 'coords needed' from the article. Pi.1415926535 (talk) 17:19, 21 September 2021 (UTC)Reply
@Pi.1415926535: I'm wondering if maybe the NTSB report was using a different coordinate datum than GeoHack does; do you know if the report's coords would resolve to an accident location that makes sense if they were to be translated from whatever different datum they're in to the GeoHack one (and, if so, whether performing this datum translation ourselves would fall foul of WP:NOR and/or WP:SYNTH)?

Addendum: if a datum mismatch is to blame, then the coordinate datum used for NTSB publications must've changed at some point between 1983 and 2017; my attempt to add NTSB-AAR-sourced coords to 1983 Anchorage runway collision was derailed by the same problem as occurred here, whereas no such trouble occurred with the coords in Ameristar Charters Flight 9363 (taken directly from one of the NTSB docket items for the accident).
As an aside, I'm not sure how the coord datum would've gotten at least a mile off-whack to begin with. The North American Plate hasn't moved that far since 1982... Whoop whoop pull up Bitching Betty ⚧️ Averted crashes 17:35, 17 December 2021 (UTC)Reply
Yeah, I don't think a datum change would be large enough. NAD 27 to NAD 83 maxed out around 100 meters, which isn't nearly enough to put it in the reservoir or the correct distance from the airport. Might be worth an email to the NTSB; I'm sure their records are detailed enough to provide proper coords. Pi.1415926535 (talk) 18:11, 17 December 2021 (UTC)Reply
