The current class from the Peterson Airman Leadership School (ALS) came out and spent a few hours with the Pete Museum on Saturday morning, 14 Aug 2010. They washed the F-89, the HAWK missiles and launcher, and did some cleaning in the City Hangar and in the Terminal. ALS is the first level of the Air Force professional military education. These are senior airmen (E-4s) preparing for promotion to staff sergeant and appointment as NCOs.
