I spent a few hours near LAX this afternoon, and noticed that planes were taking off toward the east and landing from the west.
This is the complete opposite of the way LAX normally runs; takeoffs almost always go west toward the ocean (for noise abatement?) and planes make their descent from the east, over the city of Los Angeles, onto the runways.
Could the reversal have something to do with the weather today? It's 55°F, overcast with low clouds and rain showers, but not particularly windy.
Check the landings/takeoffs out for yourself at www4.passur.com/lax.html .
I'm sure someone here knows the answer!
