Other mistake: When an aircraft is flying above the "transition altitude," which I believe is 18,000 ft. in the US, then the aircraft's altimeters are set to a standard of 29.92 millibars below that: they must be set to a local pressure to display the correct height. So when the controller at LAX is warning them that the aircraft is below 1000 ft., then he is basically telling them the aircraft is potentially higher than it actually is.
