Heat Transfer Reactor Experiment
The Heat Transfer Reactor Experiment demonstrated in 1955 that nuclear fission could power an airplane engine. But other obstacles to nuclear-powered aircraft led to cancelation of the program in 1961. In 1988, the two HTRE reactors were hauled to a visitor center at the site of EBR-I, where they remain today.
