On Jan. 23, 2012 the weather in Corpus Christi seems like it was conducive to forming aerodynamic contrails and I've watched them form under similar conditions... Cool-moderate temps, humid, cloudy/overcast/hazy, near/over water. Then we have a large airplane performing who knows what kind of landing procedure at a training base for naval aviators. C-130 pilots don't learn to fly C-130's at NASCC but that doesn't mean that some sort of C-130 training doesn't happen there at times or that even a routine landing might look odd from a particular angle.
Knowing the approximate time of day would help to better understand atmospheric conditions at the time.
Maybe I didn't make myself clear. What I saw in Corpus was pertaining to spraying, not contrails. I just saw it spraying.
Contrails is what you see in the distance, in the sky. On the contrails, cloud seeding part, I'll start another thread on that, but I have to get my notes in order.
I wasn't trying to say anybody was training in a C-130 and that they even trained there, just that there is a navy training base nearby. Sorry if I confused ya on that part.
