Question: What unique passenger system did Eero Saarinen introduce at Dulles International Airport in 1962?

Answer: Saarinen introduced controversial “mobile lounges”—vehicles that detach from the terminal to ferry passengers to planes parked by the runways. Still in use today (supplemented by later fixed gates), they were never widely copied at other airports.
