The air transport industrys future is terrifying.

The power source comes first. There is no such thing as fusion energy, and using nuclear powereven fissionon an aircraft is still in its infancy. I have gone into great depth about the efforts to create a nuclear-powered bomber, and although it is theoretically feasible, you might not want to undertake it. With 5000 passengers on board, you would need to make sure that the radiation shielding is up to par and that there is a safe route to evacuate every passenger on the ground in less than 60 secondssomething that the FAA requires before allowing an aircraft to fly. Other concerns include how this would be resupplied with food and water on Earth and where it would take off in the first placepossibly in the middle of a desert. Even the greatest goals need more than merely Finally, neither the expense nor the new engineering technologies required to construct such an airplane were mentioned.
