From Pt. Dume you'd consume at least 5000 feet of range. That would tend to limit the height of the apex.

I am no missile expert, however, it's my understanding that shoulder-fired anti-aircraft missiles can reach 15,000 feet. Like the post said, outbound departure traffic out of LAX takes a lot of traffic in the area of Pt. Dume. And northbound traffic takes it very close to the Pt. Dume area. Being only a minute or two out of LAX, a lot of the northbound traffic would certainly not be at 15,000 plus feet at that point.

The bottom line here is if a bad guy wants to bring down a commercial aircraft, it can be done, relatively easily, with a little determination. And a boat is not really necessarry to take out a westbound departure at that specific airport. I imagine even the rocks have eyes around Vista Del Mar.
