There's about a mile from the western end of the airport property to the coast, and if you look, you'll see all the roads and perhaps a few foundations for a housing development that was started but never completed. I've always assumed the property was purchased by the airport (or some agency on behalf of the airport) to avert noise complaints. Obviously once you're out over the water you don't have to worry much about noise. I can't recall ever experiencing anything like that on a flight out of LAX, and it does sound rather odd. Perhaps you were momentarily being held at a given altitude to provide clearance from other traffic. You were on a 757, which has almost fighter-like climb performance -- maybe the controller didn't expect so quick a climb. -- Karl Swartz |Home kls@chicago.com |Work kls@netapp.com |WWW http://www.chicago.com/~kls/ Moderator of sci.aeronautics.airliners -- Unix/network work pays the bills
