I think this question is legitimate, but the OP has put a generic picture of a plane in the question.
To me, this picture is gratuitous and, while adding a bit of colour, otherwise detracts from the site. I was going to edit it, but it would have been a fairly trivial edit and is also just reflecting my taste. It could plausibly improve readability and clarity. It's not worthy of either a downvote or a flag. What should be done?
"Nothing" would be acceptable.
