That all changed on 9/11, and demand for air transportation has not yet returned to peak levels. Most U.S. airlines continue to struggle for survival, and some have filed for bankruptcy. The situation makes it difficult to argue that strong action is urgently needed to avert a crisis of undercapacity in the air transportation system. This report assesses the visions and goals for U.S. civil aviation and technology goals for the year 2050.Securing the future of United States air transportationAeronautics, CommercialUnited StatesFinanceAeronautics, CommercialUnited StatesForecastingAirlinesUnited StatesFinanceAirlinesUnited StatesCost of operationAeronautics, CommercialFinance.Aeronautics, CommercialForecasting.AirlinesFinance.AirlinesCost of operation.387.7/0973National Research Council (U.S.).Committee on Aeronautics Research and Technology for Vision 2050.National Research Council (U.S.).Aeronautics and Space Engineering Board.National Research Council (U.S.).Transportation Research Board.Studies and Information Services.MiAaPQMiAaPQMiAaPQBOOK9910957497503321Securing the future of U.S. air transportation4357436UNINA
