This question, How can you identify an Airbus or Boeing from the inside?, was initially asked without much qualification, and received what I consider the best answer. It was a simple question without much qualification, and received a simple, but good answer. The original reading was:
How can you recognize a plane from the inside, when you are already sitting as passenger? In particular, is there a way to understand if you are inside a Boeing or an Airbus?
However, subsequent to that answer receiving some thirty-odd votes, the OP edited the question and inserted the qualification that:
Of course the question is related to the internal differences between the two companies, rather than on "check on your ticket" Vel "ask the hostess" Vel "read the evacuation pamphlet".
Now, I give all that as background to my question. This has occurred before, where the original good question receives good answers, which cause the OP to realize the question did not convey what they meant to communicate, at which point they change the question to something other than what was first asked. I suspect these occurrences are often tied to language barriers.
In a case like this, it would seem good to roll back the question to the original, and leave the option of asking a new question entirely.
Is it appropriate for an OP to edit a question from the original, answered version, to something substantially different? If not, how should this be addressed?
