No kidding! Watch this film of a recent NASA rocket launch. An Atlas V rocket passes near a sundog and the dog winks out as visible shock waves ripple through the air. This seemed weird to me at first because I would think sundogs don’t really have a “location” as such–it would just depend on where you’re standing. On the other hand, it’s ice crystals causing the sundog, and if the rocket passes near the ice crystals, I suppose that could destroy it. Everyone in the area saw it happen…you can hear them gasp in amazement. Here’s another view of the shock waves.
