By 10 a.m. there was a solid crowd gathered at the corner of Windsor and Ventura, enough to slow down traffic. By the time Endeavour flew over, there were hundreds and hundreds, a gathering bigger than Altadena's regular events.
The crowd was wowed by the shuttle pass-over with big shouts and lots of noise from the first moment it was spotted until it was all over with.
Afterwards the traffic lasted for 30 minutes or longer.
We'll have video of the whole experience later on at the site. For now we have the photos above.
