Tim,
Thank you for your message on my talk page. The concern is primarily that the link is being promoted inappropriately to Wikipedia. I have removed the new link you added to Philadelphia Experiment, as it appears connected to the other link you previously added (klir.com). 
f you feel the link would add great value to the article (per WP:EL) and should be re-added, please bring it up on the article's talk page and allow other editors to discuss it first.
Thanks for your understanding, let me know if you have any other concerns or questions.  (talk)
