A fact from Steel Curtain (roller coaster) appeared on Wikipedia's Main Page in the Did you know column on 18 January 2023 (check views). The text of the entry was as follows:
Did you know... that statistics for the roller coaster Steel Curtain were announced through a scratch card?

ALT1: ... that before Kennywood officially announced plans for the Steel Curtain roller coaster in 2018, the ride's statistics were unveiled through a scratch card? Source: Same as above
According to this RCDB explanation, the banana roll element only inverts riders once due to a technicality that an inversion must complete (returning riders back to a semi-upright position within 135°) before the next inversion starts. A cobra roll, a very similar element, does do this as expected, but a banana roll does not. Therefore, the RCDB entry for Steel Curtain lists the ride as only having 8 inversions (it originally listed it as 9, as did every major publication at the time of release).
Obviously, this makes it a complicated situation, as RCDB seems to be the only source pointing this out. It is a reputable secondary source performing this analysis, but unfortunately the analysis came much later after the flash-in-the-pan coverage swept the news at the time of ride's opening. Not sure if it's worth mentioning in the article at this point unless other sources can be found, but thought I'd drop a note here for future reference. --GoneIn60 (talk) 05:13, 3 July 2024 (UTC)[reply]
That is a good point. I've moved the nine-inversion figure to a footnote. Since the RCDB lists this ride as having only eight inversions, we should probably be relying on that figure instead. – Epicgenius (talk) 21:58, 1 August 2024 (UTC)[reply]
I'm not opposed, but it's still a tough call, IMO. RCDB is pretty reliable for statistics, and there are multiple people involved with gathering the data it presents, but ultimately it's a database helmed by one individual. I'd feel better about it if there was at least one other reputable secondary source out there corroborating that viewpoint. -- GoneIn60 (talk) 06:10, 2 August 2024 (UTC)[reply]
Unfortunately, I can't find other sources describing the ride as having eight inversions. I've added a footnote to the article detailing the dispute over the inversions.I do think we should change the figure back to nine inversions, since that's what generally reliable sources like CNN say. However, the RCDB figure could be included in the explanatory footnote. – Epicgenius (talk) 14:46, 12 September 2024 (UTC)[reply]
