Hi Orla Kops Thanks I appreciate your explanation I had an idea that there might be a problem due to your insistent removal of information but because you failed to include an edit summary or communicate your intention there was no way for us to know Removing sourced text without any explanation is often seen as vandalism Therefore it is best practice when editing Wikipedia to always use the edit summary or the article talk page to explain your actions Please note that Wikipedia articles can only use information which is verified by independent reliable sources that is we follow a policy of verifiability not original research You may be correct about the origin of the hangar however without an actual reliable published source we can not use that information All editors on the internet are essentially anonymous anyone can claim to be anyone and therefore we do not nor can not use any editor s word as truth As I am sure you can understand I am willing to forego inclusion of the Holland detail for the moment I don t consider it a particularly essential point But if you know of published sources which can be used to explain the history or expand the article please add them Good luck with your editing Cheers
