This photo showing the "moment a plane flies directly over a rainbow" is all over the internet at the moment.
But, despite several headlines saying so, it's not actually a photograph of a rainbow.
For starters, a rainbow is not a physical object that you can fly over.
Rainbows happen when sunlight is bent by water droplets in the atmosphere and split into individual colours. They're not actually physical objects that sit in one place in the sky (which is why you can never get to the end of a rainbow). For example, ever noticed that the sun's always behind you when you're looking at a rainbow?
