After watching the movie Trinity and Beyond for the umpteenth time yesterday, I remembered a question that I meant to ask before the Round Table forum at THR closed:
What the heck are these lines in the air next to the mushroom during nuclear testing?  

They are seen both in photographs and video of atmospheric testing of yesteryear.
Primarily, they are vertical to the mushroom, but on rare occasions, they also appear horizontal to the cloud.  Again, these are in photographs and video, so its not damaged film (the lines are captured from different angles of the same tests a multitude of times).

I have done a search on the web, but so far have found nothing.  Theres no particular reason I need to know other than to satisfy a personal curiosity.

I found a few examples after a brief search, but these are just a few examples of many. The first photograph is of those relatively rare horizontal lines, with the rest being of the typical vertical nature.  I apologize in advance to dial-up users as the last two photos are rather large.



Horizontal lines:



Vertical lines:

Smoke rockets shot just before the blast to monitor wind.

Nathaniel, that's what I suspected... the only reason I still remain curious is that none of the tests in the video show any rockets being launched in the distance before the detonation.  For example, the 280mm (?) field gun test pictured in the 6th photo displayed no such launch, at least none that was visible; nothing one second and flash, now they are there.

However, this smoke rocket explanation seems by far the most plausible idea I could think of.

Nathaniel, thanks for that link; question answered.  Wink

BTW, if you just now found that link, your net-searching skills are far superior to mine.  
Thanks again!

Yep, just searched on atmospheric nuclear testing smoke rockets.

I always figured they were the smoke trails of birds incinerated by the blast...

I always thought they were contrails of local Guardian Angels leaving the scene of the Hell man was perpetrating in the neighborhood.

Two purposes on those: To study the shock wave, and to watch where fallout is drifting.

Actually, there's some other equipment that's tasked to find out where the nuclear debris cloud is drifting...
