Its not an academic journal
Amelia, we are going to have to disagree.
However, last time I looked PPRuNE, posts were not required to meet the gold standard for academic peer review journals.
Any reasonable person using the links I provided would, with two mouse clicks been able to test the veracity of statements contained within those articles with a link to the authoritative source - the very same ones you mention.
Given the nature of the other links posted on this topic from mainstream media, I would consider the wikipedia article to of a far higher standard.
You are correct, if I was making a board submission to a business or a writing an article for peer review, I would not reference wikipedia directly, however, I may well reference the same authoritative sources wikipedia does.
