Cold, I think not. We have been consistently near 80 for awhile now. Well over the average temps.
They wanted to obscure satellite imaging and who knows what else this weekend REALLY bad.
Transponders, how do they work?The ground station usually consists of three transmitting antennas, the Primary target antenna, the Directional antenna and the omnidirectional antenna. The primary target antenna only shows aircraft without transponders if they have a reflection. The purpose of the Directional antenna is to interrogate the aircraft so it will send a reply back down to the ground station. This antenna sweeps around and the controller usually gets a 360 degree view. The directional antenna also tells the transponder to reply to Mode A and/or Mode C. Mode A is the code that you have selected on the front panel of the transponder.
Radar Theory
The ground-based ATC radar system consists of a primary surveillance radar (PSR) and secondary surveillance radar (SSR). The PSR locates and tracks aircraft within the control area by transmitting a beam of energy which is reflected from the aircraft and returned to the PSR antenna. The SSR transmits interrogation signals to the airborne radio beacon Transponder. Upon receiving the interrogation, the Transponder sends a coded reply signal back to the SSR system.

Sounding data was not conducive for this "persistent contrail theory" to be sound.

No IFR record/transponders off flying and taking part in aerosol sorties over an AFB.

I would think our security is a bit better then that. Obviously they knew well what is happening above them.

I have a really good family friend who was a captain for Continental for over 20 years. He told me that if it is commercial airliners that are leaving these chemtrails, then the pilots are doing it without knowing it. Now he didnt rule out that commercial airliners were spraying chemtrails but he did say that if they were then the chemicals were probably a fuel additive or that the sprayers were controlled from elsewhere.
Anyone who says these trails are contrails, obviously isn't very informed. A contrail lasts seconds usually less than a minute. A contrail does NOT stay for hours and spread out across the sky. They just do not.
Coming from a long line of pilots, my family has been staring into the great blue sky for a while. Only recently have we been noticing these trails. The properties of contrails didn't suddenly change. These are obviously man made occurances.
