Well, I would think that Chem11's black line he saw 3 minutes before the plane arrived would not be likely to be a shadow if it was high noon, so that is interesting and perplexing. It seems that some black lines are definately shadows. The rest still seem to have the appearance of a shadow and are aligned with their corresponding plane, but don't behave as we would expect given the position of the Sun, associated trail and position of the haze deck. |

Thermit, if the trail looks like it's below the cloud deck, wouldn't it also look like the shadow is preceding the trail?

I would certainly think that it could, 3T3L1. |

Looky! Here's an actual picture of a contrail shadow preceding its contrail! Even better, for some reason you can't see the contrail itself. (It doesn't reflect light, but it does absorb it? I dunno.)

During my recent adventure at Joshua Tree I observed black line 'tracers' preceeding CT's. The thing of it is, this ocurred well after sundown... precluding the possibility of this being a shadow being cast by the trail.
Other random observations:
The trails 'strips' that Thermit refers to were the norm, rather than exception. I witnessed planes laying CT strips directly over strips that had been previously deployed.
The trails had a more 'cloudlike' appearance. Not the smeary looking 'cloud' cover that is prevalent in the Northwest. On one ocassion, I watched the chemcover mature into what appeared to be a stormfront: dark, roiling clouds that threatened rain.
Also of interest; I experienced no adverse symptoms despite constant exposure to the trails for almost a month. Based upon my observations, I can only conclude that the focus of the operation is on weather modification in this particular part of the country... |
