The only thing is, it's not possible to take such a photo as you can't actually fly through one in the first place - a rainbow being formed by droplets above the ground and centred on a line from the Sun to the observer's eye.

The rainbow effect, while undoubtedly pretty, is actually the result of polarisation.
