It's centered over Mclellan and looks to be about a 50NM ring from the surface to 5000 on Friday. It's for the space shuttle Endeavour that they are toting around on the back of the 747. I counted 30 strips on the chart within in the ring that will all be grounded while this is going on. Seems a bit excessive to me. Please check notams if you plan on flying Friday.
