The folks at Wilco realize this and answer the problem with Airport 2000. Volume 3 provides seven interesting airports; four from Europe and three from the USA. These include Berlin Tegel, Copenhagen Kastrup, London Gatwick, Paris Orly, Denver International (my favorite), San Francisco International and Seattle Tacoma International. These airports really are unique and interesting airports, and are nicely detailed in this expansion. As for the sounds, there are some pretty good vocals in the adventures, including crew announcements and cabin calls, as well as all communication from tower to ground control to departure control, including instructions from multiple air traffic control centers, vocal captain calls and readbacks. Talk about some busy airwaves!
