Yes, it does seem that the aircraft would be dangerous to fly.
And unfortunately this is the very thing that caused the moratorium on nuclear propulsion development...fear. Fear from congress, fear from the
general populace.
We should have been heavily in R&D on nuclear propulsion systems all along, but when you get a mandate that no nuclear-powered craft can be launched,
you're pretty much pickled on development.
The next "barrier" to advancements in propulsive systems (whether you are talking about military aircraft, or space systems) that MUST be broken
down is the US populace's scaredy-cat mentality. Do you remember right after the Columbia incident, when all the debris was all over East Texas and
NASA had to issue warnings to stay away from it because of hazardous chemicals? Well, if you were watching closely there was briefly discussion that
there could be unspent hydrazine from the APUs. And there for a while there was this flury of "OMG! They're endangering our lives every time they
re-enter!!!"
How do we proceed forward when we as a society are scared of every little thing that could be a bit hazardous? Heck, IF the Columbia was lost because
of the foam you can place part of the blame of that back on this mentality. The original foam was fine...accept it wasn't "ozone friendly"...so
they had to change to "Sierra Club approved" foam that had problems from the get-go.
THIS is why I believe that a intermediate post must be established if we are to achieve some relatively "long distance" space travel. If we had an
outpost on the moon, say, we would be able to launch with alternative propulsion systems.
