The separation requirement for flying parallel and simultaneous approaches is 225 meters (738 feet). These two aircraft are at a safe distance for the approaches they
are each flying.

Due to the Lufthansa 747 being three times larger than the 757 plane and being slightly behind , gives us this incredible optical illusion.
