Air Canada flying into San Francisco, in July of 2017, at midnight was not alert enough to see they were going to crash into 4 airliners on the taxiway.... and only veered off and began to climb when about 60 feet from the ground. Landings happen on runways, not taxiways

above is the news report, and is well done, makes everything clear. Next video is only the real time radio feed, and video

Air Canada flight 759 (ACA759), an Airbus A320, C-FKCK, was cleared to land on runway 28R at San Francisco International Airport (SFO), San Francisco, California, but instead lined up on parallel taxiway C, where four air carrier airplanes were awaiting takeoff clearance

United Airlines flight 1 (UAL1), a Boeing 787;
Philippine Airlines flight 115, an Airbus A340;
United Airlines flight 863, another Boeing 787;
and United Airlines flight 1118, a Boeing 737.

ACA759 descended below 100 ft above the ground, and the flight crew advanced the thrust levers to initiate a go-around about the time it overflew the first airplane on the taxiway.
