This question asks for information about gear extension on a landing shown in a Youtube video. We already have a general question about lowering the gear and the new one covers essentially the same ground but for one specific flight. Should we allow/encourage these questions, with the risk that we open up a series of "yes, but what about this flight?" questions?
I have a general feeling that we shouldn't encourage questions that amount to speculation/comments on Youtube videos or news reports, but on the other hand the OP's interest is genuine and the question is reasonably clear.
There may be no good answer here and perhaps none is needed if we deal with things on a case-by-case basis anyway, but I thought it might be useful to see if people already have any opinions on this.
