I took a quick look around and I couldn't find previous discussion, so I thought I would bring this up.
I was inspired by this question, which asks about whether jet fuel can melt steel beams (yes, it's that kind of question). While that particular question didn't seem to be asked in good faith, there are many people out there who could benefit from some engineering insight into common conspiracies like this.
That question got a lot of downvotes, probably because the asker didn't really put much effort into it beyond giving some statistic on fuel temperatures, and became combative when an answer was given. However, the downvotes may have also been a sign of displeasure from the community; after all the particular "fuel temperature" problem is often discussed and much-maligned.
My question is: assuming the questions and answers are properly moderated (avoiding spam, speculation, and insults) how should the community handle these questions?
Should we try to give a solid engineering answer and move on? Should they be marked as off-topic (maybe Skeptics SE is a better place for them)? Or should we treat them as spam and close them?
I'm looking for some solid discussion about a problem that will likely not go away, we might as well think about how to deal with it now.
