Darren,

I would have to agree with you on that NWA 869 would have been a massive light show 4,400 years ago (Thank you everyone :) that answer my question) because it represents one of the largest finds in the Saharan desert. The total weight so far that has been recovered is about 7 metric tons which comes to about 15,432.3584 pounds. It is said that before entry, NWA 869 was about 120-230 metric tons, which means that 90% to 95% of the mass was lost due to ablation during atmopheric passage. That would have been a sight to see, sun glasses anyone?

>(W1). I am guessing 4.4 kyr means 4.4 years from the low level


BTW, if 869 had fallen just 4.4 years before it was found, there would be camels
that are still running today. The light show from that entry had to be MASSIVE.
