RE: Land Side-by-Side Craters, Chad / Almahata Sitta Meteorite

RE: Land Side-by-Side Craters, Chad / Almahata Sitta  Meteorite

Mr. Kramer wrote,

"Wasn't Chad where they found those meteorites
not too long ago? The ones from the observed meteor
strike."

You might be thinking about the Almahata Sitta
Meteorite, which fell in Sudan in 2008. It was the first
one observed and predicted to impact Earth while it
was still in space. When it did fall to Earth, it made a
spectacular fireball. Some articles are:
