Original Note:
This rainbow contrail is formed when air pressure and temperature over the wings drop, causing the water vapor to freeze into different-sized droplets. When backlit by the sun, these frozen water droplets refract the light at different wavelengths, appearing as a rainbow. https://www.space.com/rainbow-contrail-photographs
