I couldn't find a good article in English, the one I pasted was very poor on details. Here is a Google translation (sorry) of a Bulgarian website - http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&eotf=1&u=http%3A%2F%2Fpan.bg%2Fview_article-6-9985-V-Syrbiq-otbelqzaha-tyrzhestveno-godishninata-ot-svalqneto-na-nevidimiq-F-117.html http://translate.google.com/translate?sl=auto&tl=en&... . The plane was on their screen the whole time. That's their radar - http://en.wikipedia.org/wiki/P-18_radar http://en.wikipedia.org/wiki/P-18_radar , it has been in use since the '70s, the latest ones manufactured during 1984. P.S. The translation says "you downloaded 'stealth'" in one place. Believe me, they mean "you took down 'stealth'". It's not one of those "you wouldn't download a stealth bomber" things. P.P.S. What does the standard say, if I start using apostrophes in a paragraph because the quote contains double quotes in it, should I use apostrophes for all my quotes or could I just switch back to double quotes?
