Interesting video

I'm sure many (if not most) of you have seen some of the footage shown here before. However, trust me, it's still worth taking the time to watch this video:

I have never ever seen or heard of the effect depicted at the end of the video after years of reading every aviation book I could get my hands on and watching every show I could. Well worth watchin it :)

streak, it seems, that's a new one, never been seen before by anybody, well according to what I read anyways.

 

What happened was a sun dog, ring around the sun, got "evaporated" by the rocket's shock wave. The shock randomized the ice crystal orientation. In the sun dogs, the crystals align aerodynamically as they fall and so act together collectively on to make sunlight into rainbow colours (say like DVD surface -- ah sorta). But with all the crystals shocked into random orientation, the effect vanished.

 

Well that's what they said anyways.

Other shots of that. I searched tube for "rocket sundog" and got these...

That was a great launch. You had to be close to see it, though, it wasn't visible from more than about 15 miles or so.
