In respect of the weather sat image posted earlier in this thread, I posted it on a local non aviation forum and described the concentric contrails as being formed over East Anglia and blown over the North Sea by a SW wind but a reader of that forum has posted a differing opinion and contends the contrails were formed over the North Sea and were blown towards East Anglia by a NE wind.
As there is no date on the satellite image I cannot look in the weather archive to confirm the wind direction either way.
Help!

They seem to be formed over the North Sea as they get more dispersed as the head over Eastern England.
If that were the case, it would suggest the contrails originated overland with the latest contrails at the time of imaging being over the North Sea i.e a SW-NE track.
However, I think the image was taken on 15 Apr 1993 if its the same one as I found on another old thread. That one looked like EO / false colour where as this one is a radar image, so I can't be 100% certain.

The contrails of the North Sea do look tighter, and appear to 'originate' from a known orbit area in the N. Sea. The contrails over land, however, do not correspond to a designated orbit area.
The picture suggests the aircraft had orbited over a dozen times and, with each orbit taking the same time in minutes as is the radius of the orbit @300kts, thus making the total time in the observed orbit as around 3 hours. The vector of the contrail therefore suggests a prevailing wind at altitude of ~030 degrees @60 kts.
All very '-ish', maths-wise, I should add.

As E-3 orbits are situated away from airways and areas of high activity, it would seem logical that the orbit is over the N.Sea.... it would be most unusual for an E-3 to be sitting over the Home Counties.
I don't own this space under my name. I should have leased it while I still could
Do they orbit the other way south of the equator?
I thought the dome rotation had to be changed every 100 turns as it would either over tighten too tight or unscrew and come off./

Nice to see members of the USAF playing with the chemtrail community! The chemtrail buffoons actually thought the KC-10 crewmember was a whistleblower!

The video shows a KC-10 forming an aerodynamic contrail.

Given that the contrails can be seen both from the ground and from space surely any self-respecting crew would be trying their utmost to stop merely giving us circles and draw a massive cock in the wide blue yonder?

Cost me a sh1t load of beer tokens after landing though.

Some very senior Jockistani god-botherer rang Leuchars and explained that his flock were rather miffed at the obscene item floating overhead. "Very sorry", he was told, "we'll sort it out!". A significant number of Meteors launched, then formed up in line abreast before flying through the floating cock. Some deft manoeuvring and they reappeared at 90º off the earlier attack heading, completed the task and went home for tea.
The result being that, if no-one had loooked up and noticed the aerial phenomenon in the first place, they certainly saw it after the attempt to cross it out!
As I said, a tale. It may not be true, but I'd like to think that it is!
