content_pasteAdvanced Tactical Fighters was the sequel to Marine Fighters, and third in the series. It introduced stealth and vectored thrust aircraft. I remember the first time sat in my hom-buil cockpit and booted it up on my 486 DX-66. I leapt into the Grumman X-31 and headed for the clouds. For a while I was convinced there was something wrong with the program because this aircraft just seemed too fast!
