This is a great optical illusion. Would you believe that the below optical illusion of two jets flying next to each other is actually done entirely with paint?
Of course you wouldn't. At first glance though a paint job might just cross your mind. But there are too many wheels and tails for this to be done with only paint.
The truth is that here we have A Lufthansa 747-400 and a United 757-200 landing at the same time on parallel runways at the San Francisco International Airport. These two runways are separated by about 225 meters.
This optical illusion of two planes merging in midair seems almost real due to the Jumbo being 3 times larger than the 757 and being slightly behind.
