Hello Again,
Someone working closely with this new Egyptian iron meteorite
contacted me and said the scientific work has been done. Official
Egyptian expeditions have confirmed the crater as well.
Looks like there is indeed a new Ataxite, how exciting!

Some people are born on third base
and go through life thinking they hit a triple.
