Speedy deletion nomination of Jay Hunter Morris

If this is the first article that you have created, you may want to read the guide to writing your first article.
You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Jay Hunter Morris requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about a person, organization (band, club, company, etc.) or web content, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable.

If you think that this notice was placed here in error, contest the deletion by clicking on the button labelled "Click here to contest this speedy deletion". Doing so will take you to the talk page where you will find a pre-formatted place for you to explain why you believe the page should not be deleted. You can also visit the page's talk page directly to give your reasons, but be aware that once tagged for speedy deletion, if the page meets the criterion, it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the page that would render it more in conformance with Wikipedia's policies and guidelines. If the page is deleted, you can contact one of these administrators to request that the administrator userfy the page or email a copy to you. Themself (talk) 02:01, 6 November 2011 (UTC)[reply]

Response: I understand why the article was a candidate for speedy deletion. What I should have done was prepare the article offline as far as I could and then posted it. Sorry for the hassle.

Re:HUD design factors

Left some response at my talk re: these adds look good. BTW Checking up on this I see one more design factor, Mechanical/ergonomic limitations - for example a diagram at one of the refs show how the optical path has to be redirected at a right angle to make a device housing that would clear the path of the pilots knees in an ejection. These design factors look to effect other design factors such as Collimation, Eyebox, FOV since there is a limit to the size of the optical elements/optical path, you are only going to get an FOV and Eyebox that is considered "good enough", can't afford anything bigger space wise. Something to ref and add. Fountains of Bryn Mawr (talk) 20:46, 14 November 2011 (UTC)[reply]

You're absolutely correct on the mechanical/ergonomic design considerations. In the civil world, HUD installations must be designed (and certified) to comply with HIC requirements...HIC = Head Injury Criteria. In the civil world, this means that in the event of a sudden aircraft stoppage (a runway over-run, aircraft striking a dike or localizer antenna structure, perhaps) the HUD combiner must swing out of the way before the forward motion of the pilot's head goes through it.
