Deletion of Air Napier

Comment: You are confusing "I think this is an important subject" with what Wikipedia means by notability. You may think that this article should be kept, but on Wikipedia companies need extensive independent third party coverage beyond directory listings to be "notable" and clearly this subject doesn't have those references. As  says "if no reliable third-party sources can be found on a topic, then it should not have a separate article", which is the case here.  explains this in much more detail

Comment: Those have been added by well-meaning editors trying to show notability, but, as you note, the very fact that they are the best sources available and make mere passing mentions only serves to underline how far short of  the subject falls
