Can anyone let us know what aircraft or aircraft in the same incident
killed thousands of people on the ground?

He's referring to the World Trade Center attacks on 9/11/01.

I am interested in aircraft accidents but I do not know at the moment of
any that fit that category.

That's because it wasn't an accident, and was so clearly irrelevant to this
thread that it wouldn't be surprising for a reader to not figure out what he
was talking about in this context.
