现代飞机这么早就扔博物馆了？模型吗？
根据该博物馆网站介绍，这里的娘娘和幽灵并非模型，而是曾经用于测试的真机。其中，幽灵并未安装发动机等设备，仅用于疲劳测试：

"The aircraft on display (S/N 91-4003) was one of nine F-22s built for Engineering, Manufacture and Development (EMD) testing, and it rolled off the Lockheed Martin assembly line in Georgia on May 22, 1999. Assigned to the 412th Test Wing at Edwards Air Force Base, Calif., the aircraft made its first flight on March 6, 2000. After completing its phase in the test program, this aircraft came to the museum in January 2007. It is painted to represent an F-22A flown by the 1st Fighter Wing at Langley Air Force Base, Va. "

"Northrop Grumman constructed two additional aircraft without engines or instruments for fatigue testing. On the second of those test aircraft (the B-2 on display at the museum), engineers attached computer-controlled, hydraulically driven plates along the airframe to simulate all flying conditions. They calculated that the structure would reach 150 percent of the design specifications, but the wing withstood stresses over 161 percent before it finally cracked.
Early production B-2s also underwent extensive environmental testing. In 1993 the Spirit of Ohio (S/N 82-1070) endured more than 1,000 hours of extensive temperature testing at the McKinley Climatic Laboratory at Eglin Air Force Base, Fla. It withstood temperatures ranging from -65 to 120 degrees Fahrenheit, rain and high humidity. To verify the test results outside the laboratory, the Spirit of Ohio deployed to Eielson Air Force Base, Alaska, in March 1996 for further cold climate testing. To signify these tests, the technicians painted the "Fire and Ice" artwork on the nose landing gear panel and signed it. Presented to the museum in 1999, that nose panel was installed on the museum's B-2 during restoration. "
