Not significantly only slightly, but still disappointing considering the new millenium was supposed to be all futuristicy and awsome, not all Michael Jacksony like the last 2 decades...you know what i mean? DE evolution?
I remember hearing it in flight simulator games and one time at an airshow. It's like a buzzy alarm noise that oscillates in a weird pattern. I think it happens when the pilot switches to A/A radar, could it be the jamming equipment?
