The National Air and Space Museum is currently developing a major permanent exhibition on aerodynamics. Entitled HOW THINGS FLY, it will include about 20 interactive stations. It's scheduled to open sometime in 1996. You can get more information about it by contacting the project developers (for whom I don't have e-mail addresses): Barbara Brennan, NASM 3128 stop 316, 601 Independence Avenue SW, Washington, DC 20560 (202-357-2 975), and Christopher (Kit) Stetser @ the same address but a different room # a nd mail stop, i.e., NASM 211 stop 305 (202-786-2106).
