Yeah, though this wasn't just luck: as I read, the F-117's used the same route several times, and Colonel Dani's battery was placed on that route deliberately. Indeed, the hardest part is to get that F-117 on the SNR screens, especially since we don't know its altitude, as P-18 is a 2D radar, that does not provide altitude information.
Yes, that's correct and that's why I also put the word LUCK between "Quotes" ("luck"). Luck helped but the mistake of using the same ingress route over and over again also "helped" the Serbians a lot
