Are y'sure L'Hospital's quinticde l'hospital/quintique de l'hospital.shtml doesn't get used? (Wish I knew its English name.)142.177.24.163 03:49, 19 Aug 2004 (UTC)

the corkscrew at knott's berry farm also claims to be the first modern steel looping coaster, also opened in 1975. Anyone who knows which is true could maybe put a note in explaining the discrepancy?wimbledon andy14:28, 24 August 2006 (UTC)[reply]

Were the high G-forces (>6 G) of a circular loop really the main source for injuries? I would suspect another mechanism: If the a more or less straight track is followed by a circular loop there not only a sudden onset of maximum G-forces but also an extreme angular acceleration: The car (and the passenger sitting inside) is forced to a fast rotation at once. Due to inertia the passenger's head is pulled foward when the loop starts and forced backwards at the exit. Especially the forward pull may cause neck injuries similar to those after a (moderate) car crash. The "Thriller" coaster is an example that near-circular loops are possible if the entrances and the exits are made clothoide-shaped. The G-forces of 6.5 G were slightly higher than at the "Nessie"-Loop (Hansa-Park Sierksdorf, Germany, 5.6 G) or theOlympia Looping (5.2 G).--SiriusB14:59, 23 October 2007 (UTC)[reply]

What is the purpose of this graphic? Either it has a purpose in explaining the clothoid loop and should be mentioned in the article or it doesn't and should be removed.Riph (talk)06:34, 24 January 2008 (UTC)[reply]

I've removed it. The term "clothoid" has led to confusion, we should not use it unless it can be properly backed up with an etymology and parametric equation; whatever it is, it isnot aCornu spiral! --The Anome (talk)11:02, 13 March 2008 (UTC)[reply]

Update: I've now added a sourced explanation of the term "clothoid loop". It uses sections from the Cornu spiral, and should not be confused with the clothoid itself. The image stays removed: it seems not to be an illustration of either. --The Anome (talk)13:40, 13 March 2008 (UTC)[reply]

Every single interwiki-linked article is about a flight manoeuvre, and this article is about rollercoasters. Is it a joke? This article should be unlinked from the others.Wizardist (talk)16:16, 9 September 2012 (UTC)[reply]

Maybe the interwiki links need to be updated, in that case. That use would be included atAerobatic maneuver—there isn't nearly enough burden to make "Vertical loop" redirect to the aerobatics page.czar · ·04:35, 26 August 2013 (UTC)[reply]

Hello fellow Wikipedians,

I have just modified one external link onVertical loop. Please take a moment to reviewmy edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visitthis simple FaQ for additional information. I made the following changes:
