Thanks so far Guys! I was thinking about North Island too.
For now my route would look a little like this:
6AM dep El Segundo (Due to jetlag I'll be awake at 4AM anyway
8AM arr North Island, spend time on the beach under the approach
10AM Take the boat tour around North Island
11AM dep San Diego
12AM arr Carlsbad Palomar for some general aviation
1PM dep Carlsbad Palomar
2PM arr March AFB museum
3PM dep March
4PM arr Long Beach for C-17's and civil
6PM dep Long Beach
6.30PM arr In 'n out burger at LAX until dawn.
Anyone more tips to see more aircraft on one day?
Oh, BTW: I could find some mention about a museum in Hawthorne, but not the museum itself. Anyone for coordinates?
