We have an accepted cosmic airburst event in recent history -- has anyone found substantial numbers of nanodiamonds as a result of Tunguska? If (compared to 'normal' background quantities) more were found in that area and could be linked to the airburst/impact, that would help substantiate nanodiamond deposits as an indicator. For that matter, what about comparing it to other confirmed mega-impact areas? Do the impactite layers also contain elevated levels of iridium? There are other markers that could bolster this theory.
