kmz for notam (opens in google earth)
!HHR 11/014 ZLA AIRSPACE UNMANNED ACFT WITHIN AN AREA BOUNDED BY LAS035020 LAS035007 LAS290040 LAS310040 FL220/BLW WEF 1211091600-1211112300
This is an odd NOTAM. They usually fly the UAVs over the Nellis range. This NOTAM goes as far south as KVGT (North Las Vegas airport). It goes far
enough north to reach Creech.
The time window is 11/09/2012 16:00z to 11/11/2012 23:00z or
11/09/2012 8AM to 11/11/2012 3PM. The hours are over the weekend, and Nellis is having an open house, but the area doesn't reach Nellis.
FL220 is 22kft MSL. That is flight 22kft and below, but plenty of commercial traffic in that range.
