Sonic Boom Meets Sun Dog from barbara tomlinson on Vimeo.
A sun dog is apparently a bright light or rainbow effect caused by light refraction through ice crystals. This is actually a pretty cool video that shows a the sonic boom from a rocket blasting through a sun dog and causing a cool effect (it happens at about the 1:50 mark).
My question is this: why do rainbows make people sound like idiots?
