The introduction of air traffic control concepts like ""omnidirectional range"" and ""stacking point,"" and organizations like the FAA and the Operations Briefing Office makes this somewhat more complicated than previous Let's Go visits. And except for photographs (which have a real advantage with this kind of subject matter) this simpler presentation includes all the most interesting elements of Richards' Jetport (see below). Also the worn-out device of using a hypothetical child visiting a hypothetical relative as an excuse for the guided tour has been wisely abandoned.
