Will aircraft ever fly on nuclear power?

Wow. Err. Perhaps not that great an idea.

I understand the need for alternatives to huge amount of fuel aircraft currently consume, but nuclear energy seems perhaps the wrong approach.
Maybe development of superior battery technology would be a better priority.

I'm looking forward to when fusion power is worked out though. That will be quite a break through, and can't be adopted fast enough really. Also, thorium reactors could be a nice stop gap.
