Saw a H-60 at school, roughly 3000 ft., went home, surprisingly I found him on 127.15 (Monterey Approach/Departure). From 129th @ Moffett (Mountain View). 1500 local. I heard a flight of 3 from Lemoore. Didn't catch a callsign. 1600 local. 290.5 Descend from FL 200 to FL 160. Switch to 307.0. Cheers! John in Salinas, CA
