Two aircraft aborted their landings at the San Francisco International Airport in California on May 19 after sighting another plane on the runway—part of a string of dangerous aircraft safety events occurring recently.
The incident involved a United flight and an Alaska Airlines flight aborting their landings. The planes were cleared to land on two different runways. However, a Southwest flight moved across these two runways, forcing both pilots to abort the landing and pull up. Both planes circled around for some time before landing.
