Those books had hi-tech cool stuff also. Disclosure had the whole VR thing. If you remember he ran into someone in the VR file system. Rising Sun had a bunch of imaging technology in it. Centered around USC, basically how pictures can be manipulated now and how they unmanipulated it. Can’t really remember Airframe, just all that plane info I guess.
Incidentally, these 3 books aren’t like most of his books that have terrible endings. Disclosure and Rising Sun had decent endings. Airframe essentially didn’t have an ending; totally awkward. The movies sucked though.
