My notes from the video:

-Rocket booster is 30 meters x 5 meters
-It is tumbling now
-orbits the earth every 90 minutes
-10 percent chance to hit a populated area.
-Its current weight with no fuel etc is 21 metric tons
-pieces as large as 5 tons are expected to hit the Earth's surface. (an American pickup truck weighs 2 to 3 tons)
-most people on the forum are too young to remember the re-entry of Skylab but it was huge back in the day, on the news every day. This was 40 years ago and it was the largest thing ever to re-enter the atmosphere. This new booster is way bigger.

But it should make for some spectacular viewing as parts of it burn. I hope I can see it.
