"Chad Irby" You should remember that with small fission warheads at high
altitudes,
there is very little fallout, and practically zero compared to even a
single megaton-level ground strike.

What makes you think that these would have been high level blasts???
Tactics with the B52 was a ground hugger to avoid SAMS and radar detection.
Incinerating a Bear full of nuclear warheads would have created a severe
nuclear fall out problem!

Not to mention that they planned on using the same size of warhead over
most of the continental US for air defense..

U.S. Bomarc sites were near the Canada/U.S. border and most intercepts
would have taken place over Canada.. Bomarc bases were hard sites. Fighter
aircraft like the CF-105 would have been dispersed all over the country to
forward bases in the event of an attack. They could also have been able to
be called back in case of an error. A Bomarc was a one way trip!
