A Lufthansa 747-400 and a United 757-200 are on a simultaneous
landing on the parallel runways 28L and 28R at the San Francisco International
Airport (SFO). Real runway separation is 225 meters. Due to the Jumbo being
3 times larger than the 757 and being behind gives us this fantastic
optical illusion seeming to fly too near together...
