"I wonder if Hart was the source of the warning to "not fly" that was given to San Francisco Mayor Willie Brown. (IIRC, Willie got that warning a day or so before 9-11; but I don't think the source was named in the newspaper report I saw.)"

I remember this too. Was there any investigation into how Brown got the warning and why the people on the 4 planes didn't?

Was there any investigation into how Brown got the warning and why the people on the 4 planes didn't?

I haven't heard of any; but I am in Southern California.
Seeing how we hear about the Pro-Palestinian protests in the Bay Area fairly often
(including the bru-ha-ha over the 11-year old girl who got arrested for assault on a cop),
maybe one of Hiz-zonor's Palestinian-American or Muslim-American constituents just couldn't
let Willie get splatted.
