The SWA and JAL aircrafts you are talking about are landing on parallele runways. So, that is not the incident Oystein is talking about.
Near misses happen all the time indeed, in the air, on the ground as well...
You have the tower monitoring landings, take offs and grounds, then you have several stations based in L.A. Orange County, San Diego, etc. all handling various parts of the sky, up down and side ways... lol
You have airplanes missing their landing who have to put back the power, and then have just enough fuel to turn around and try again...
It still safer to fly than to cross the street
