Hi Jason -

You're absolutely right about air blast. I myself
never suggested it.

Returning to the data, as one can see from the C14
calibration adjustment at 10,900, impactor speed may
be important in the freeing of neutrons. I don't think
I would be making a mistake to say that comets
generally have a higher speed of impact than
asteroids.

Suppose then that we have an iron moving at a very
very high rate of speed. Could such an impact then
also release neutrons, as shown at 31,000 BCE by the
C14 calibration curve?

Then might you not also have re-entry from space some
distance from the point of impact of vaporized and
condensed iron spherules? And thus tusks peppered but
not crushed?
