“That might be an option .. 100 years from now.”

The first operation of a nuclear aircraft engine occurred on January 31, 1956 using a modified General Electric J47 turbojet engine.

Hydrogen fuel cells will be one of sources. At some time out
in the future don’t discount nuclear. Keep in mind that we
have progressed from burning wood to where we are today.

Have a good evening...
