[meteorite-list] Odessa

The C14 calibration data only goes back 24,000 years, and there have been no 
confirmed significant impacts during that time, and not even any well dated 
minor impacts. So how can spikes in the calibration curve be linked to 
impacts?

Even given a large impact (a big given), there are plausible explanations 
for how this would affect C14 concentrations; far more plausible than the 
very unlikely production of neutrons.
