I saw us staff up well for it, and thank you for that. But I only saw one plane leave the US for one of the event arrival airports. A real shame for all those controllers in the ARTCCs who geared up and participated. The good news, of course, is that our facilities were very well staffed and lots of nonevent pilots got a chance to enjoy great ATC.
I agree with Matt; the advertising for the event pretty much sucked. The event organizers would have to answer the OP's question, though, about why it wasn't more heavily advertised and talked up.
Hopefully, this will be a lesson learned and the advertising and excitement will be ramped up several notches next time.
